Purana Quila (Old Fort) - Sher Shah built the Purana Quila in Delhi. Started by him, it was completed by Humayun. Built of red and buff sand-stone, it is ornamented with black and white marble and coloured tiles. A beautiful mosque inside the Quila with ornamental arches, decorative panels, geometrical designs and inscriptions is an example of the development of architecture and ornamentation during Sher Shah's reign.
Sher Shah's tomb, Sasaram - Sher Shah's tomb at Sasaram in Bihar built in 1549 is in the centre of a large square tank and rises al 46 metres high. It is a two storey construction on a terraced platform. The upper terrace has pillared domes and the two storeys above have a pillared kiosk at the four corners. The base of the large central dome has thirty two sides. The tomb is decorated with coloured tiles, very few of which remain now. Entrance to the tomb is through a domed structure.
Humayun's Tomb - Humayun’s tomb was built by his widow Haji Begum in 1565 A.D. in Delhi in 1569A.D., fourteen years after his death. The mausoleum stands in the centre of a square enclosed garden. The garden is divided and sub-divided into squares, typical of Mughal gardens. The lofty double storeyed structure is built on a huge high platform terrace which has a row of calls with arched openings. The central chamber is octagonal in shape and contains the tomb. Each side of the mausoleum has a large arched alcove in the centre with smaller ones on either side. It has a high marble double dome in the centre and pillared kiosks with cupolas surrounding it. Built of red sandstone with an inlay of black, white and yellow marble it presents an imposing picture. Planned by a Persian architect and constructed by Indian workers, it is a combination of both Persian and Indian styles of architecture. Entrance to the mausoleum is through two double storeyed gateways.
Agra Fort - A greater part of the fort at Agra was constructed by Akbar starting in 1565 AD and completed it in 1574 A.D. Situated on the bank of the river Jamuna, it is a massive and grand structure. The special feature of this fort is the 2.5 kms. long and 21 metres high circuitous wall of solid red sand stone. The stones are linked with iron rings so close that not even a hair can pass through. The entrance to the fort is through two gateways. The main entrance known as Delhi Gate was the ceremonial entrance to the fort. The other smaller gateway is called the Hathi Pol or Elephant Gate because of the two huge elephants on either side of the gate and was meant for private use. The Delhi Gate entrance archway is flanked by two double storeyed octagonal bastions crowned by octagonal domed kiosks. A balcony separates the two storeys. The structure above the balcony has arched recesses. The gateway is decorated with beautiful panels of coloured tiles and marble inlay work. The fort is surrounded by a deep moat. The fort formerly contained numerous buildings of red sand stone but these were later demolished in the reign of Shah Jehan who constructed marble pavilions instead. Some of the important buildings inside the fort are the Jahangiri Mahal built for Jahangir and his family, the Moti Masjid, and Mena Bazaars. The Jehangiri Mahal is an impressive structure and has a courtyard surrounded by double-storeyed halls and rooms. The corbel brackets, doorways and the chajja above them are profusely carved. The elaborate architecture of the brackets seems to be an imitation of wood work. The planning and construction of the fort show that Rajput architectural styles were freely adopted.
Fatehpur Sikri - Akbar’s greatest architectural achievement was the construction of Fatehpur Sikri, his Capital City near Agra. The construction pf the walled city was started in 1569 A.D. and completed in 1574 A.D. contained some of the most beautiful buildings – both religious and secular which testify to the Emperor’s aim of achieving social, political and religious integration. The religious edifices worth mentioning are the Jami Masjid and Salim Chisti’s Tomb. The tomb built in 1571 A.D. in the corner of the mosque compound is a square marble chamber with a verandah. The cenotaph has an exquisitely designed lattice screen around it.
Panch Mahal - The secular ones include Jodh Bai’s palace, the Panch Mahal, the Diwan-i-khas and the Buland Darwaza. Jodha Bai's palace is a large building consisting of rooms on all four sides of a courtyard. The centre part and four corners of the building are doubled storeyed. A small chapel attached has niches in the wakks for idols. The panch Mahal is a five stored structure, each storey smaller in size as they go up, the last one being only a kiosk.
Buland Darwaza - A magnificent gateway was added later in 1571-72 to commemorate his conquest of Gujarat. Built of red sand stone and marble it is said to be the “most perfect architectural achievement in the whole of India". A flight of steps lead to the gateway which is about 53 metres in height and 39 metres in width. Entrance is through a huge arched domed recess. A broad rectangular strip bordering the archway has calligraphic inscriptions on it. At the corners are slender turrets. The beautiful perforated parapet and the row of kiosks with cupolas add to the dignity of the monument. An inscription on the gateway testifies to Akbar’s religious toleration.
Akbar's Tomb, Sikandra - The Mausoleum of Akbar at Sikandra near Agra was started by Akbar and completed by his son Jahangir in 1612 A.D. who changed the original design of his father. Designed on the model of a Buddhist Vihara, it is set in the centre of a square garden. The enclosure wall on each side has a gateway. The main gateway has four white marble minarets in the four corners. The Mausoleum has five terraces, rising from the basement, one above the other, diminishing in size as they ascend. The red sand-stone entrance gateway is the largest and is richly decorated with inlaid coloured stone work. With its charming proportions, it is by itself a work of art.
Itmad-Ud-Daula’s Tomb: - The Mausoleum of Itmad-ud-Daula, the revenue minister of Jahangir and Nur Jehan’s father was built in Agra on the banks of the Jumuna. Started by Jahangir it was completed by Nur Jehan in 1628 A.D. A small rectangular structure in white marble, inlaid with semi-precious stones and coloured glass, it is a delicate and beautiful piece of architecture. It is the first pure marble monument and differs from the typical massive, red sand-stone structures of earlier Mughals. Situated in a garden amidst fountains, it has a square lower storey with four minarets in the four corners. A traceried pavilion forms the second storey. A central chamber inside contains the tombs and is surrounded by an enclosed verandah. A jewel in marble-“there is no other building like it in the entire range of Mughal Architecture”.
Soon after laying the foundation or his new Capital city of Shahjehanabad Shah Jchan started construction of the red sandstone Red Fort or Lal Quila in 1638 A.D. on the banks of the river Jumuna. The fort took nearly nine years to complete. Within the walled city, the fortress is in the shape of a rectangle 900 metres by 550 metres. The rampart walls are about 34 metres high. A moat surrounds the rampart. Two of the five gateways of the fort are three storeyed structures flanked by octagonal towers. These are the Lahori Gate and the Delhi Gate. Figures of two huge elephants flank the Delhi Gate. The main entrance to the fort is through the Lahori Gate. A covered passage with shops on either side leads to the palaces inside the fort. Barracks for soldiers, audience halls, horse and elephant stables, and ornamental gardens are other features of the fort.
Some of the beautiful buildings are the Diwan-i-Am, Diwan-i-Khas, Moti Mahal, Hira Mahal and Rang Mahal, the latter three, all halls decorated with pietro dura and patterns in gold and colour and floors paved with marble slabs. The Moti Masjid was added later in 1654 A.D. and is an excellent specimen of the balance and rhythm maintained in Mughal constructions.
The Diwan-i-Am (Hall of Public Audience) is an arched pillared durbar hall. A white marble throne, embellished with coloured inlay work stands under a marble canopy. Below the throne is a marble dais inlaid with semi-precious stones. Behind the throne, the wall has beautiful panels of flowers and birds in coloured inlay work.
The Diwan-i-Khas (Hall of Private Audience) is a rectangular central hall with aisles of arches and painted pillars. The four corners of the roof have pillars with chhatris on them. The walls have the famous verses of Amir Khusro which says that “If there is paradise on earth it is here”
Taj Mahal - The Taj Mahal in Agra, a dream in white marble was built by Shah Jehan as a memorial to his beloved wife Mumtaz Begum. Built on the banks of the river Jumna, it was started in 1632 A.D. and took 22 years to complete. Marble from Makrana and precious stones from different parts of the world were used in its construction. Planned by Isa, a Persian architect it is a masterpiece of architecture. The Taj is situated in the centre of a high marble terrace. A marble minaret of four storeys stands on each of the four corners of the terrace. The minarets are crowned with domes. The main structure is a square. A huge, vaulted recess with smaller arched recesses in two storeys on either side make up the facade of the building on all sides. An octagonal hall with an exquisite perforated marble screen contains the cenotaphs of Mumtaz and Shah Jehan. The vaulted ceiling is crowned in the centre by a large bulbous dome which tapers off into a foliated crest. Around the dome are four cupolas. The surface of the walls – exterior and interior and the cenotaphs are beautifully decorated with pietra dura, floral and geometrical designs. Borders of inscriptions decorate the main archways.
Shah Jahan - Rather than building huge monuments unlike his predecessors, Shah Jahan built elegant edifices.His predecessors built huge buildings to demonstrate their power.The force and originality of their building style gave way under to a delicate elegance and refinement of detail, illustrated in the palaces erected in his reign at Agra and Delhi. Some examples include the Taj Mahal at Agra and the tomb of Mumtaz Mahal, the wife of Shah Jahan. The Moti Masjid (Pearl Mosque) in the Agra Fort and The Jama Masjid at Delhi are imposing buildings, and their position and architecture have been carefully considered so as to produce a pleasing effect and feeling of spacious elegance and well-balanced proportion of parts. Shah Jahan also built the Tomb of Jahangir and sections of the Lahore Fort that include the Moti Masjid, Sheesh Mahal, and Naulakha pavilion which are all enclosed in the fort. He also built a mosque named after himself in Thatta called Shahjahan Mosque. Another mosque was built during his tenure in Lahore called Wazir Khan Mosque, by Shaikh Ilm-ud-din Ansari who was the court physician to the emperor.
