Lalbag Fort

Lalbagh Fort (Bengali: লালবগ কেল্লা, also known as Fort Aurangabad) is an incomplete 17th-century Mughal palace fortress situated in the southwestern part of Old Dhaka, Bangladesh, on the northern bank of the Buriganga River. Construction was commenced in 1678 by Prince Muhammad Azam Shah, the third son of Emperor Aurangzeb, during his brief 15-month vice-royalty of Bengal; however, the project was halted when Azam was recalled to Delhi, and his successor Shaista Khan, who resumed work around 1680, also abandoned it—reportedly after the death of his daughter Pari Bibi in 1684, which was considered an ill omen—leaving the complex perpetually unfinished. The rectangular fort enclosure spans approximately 19 acres and follows the traditional Mughal charbagh (four-part garden) layout, with its defensive walls featuring five two-story bastions along the southern face and two along the western face, the largest of which sits near the main southern gate and contains an underground tunnel. The three surviving gateways include the imposing southern gate, a three-storeyed ceremonial structure with a tall central arch, semi-octagonal balconies, decorative panels, and slender minarets, though its upper storey was never completed. The central area of the fort is occupied by three principal buildings arranged in a line: the Diwan-i-Aam (Hall of Audience / Governor's Palace), a two-storeyed red brick building on the east that now houses a museum of Mughal artifacts, with the single-storeyed Shahi Hammam (Royal Bathhouse) attached to its west, featuring an underground room for boiling water, a masonry brick bath-tub, and intricate geometric patterns and Persian calligraphy in its interiors; the Lalbagh Fort Mosque (Quilla Masjid) on the west, a rectangular structure with three ribbed domes buttressed by four corner octagonal minarets, considered one of the finest examples of Mughal-Bengali architectural amalgamation; and the Tomb of Pari Bibi at the center, the most impressive surviving structure, a white marble mausoleum whose plan resembles Humayun's Tomb in Delhi, with eight rooms surrounding a central square chamber covered by a false octagonal dome wrapped in brass plate, its inner walls clad entirely in white marble and its corner rooms adorned with beautifully glazed floral tiles. A large square water tank (approximately 71 meters on each side) sits in front of the Diwan-i-Aam between the southern and northern gateways, and the fort's western side once accommodated a roof-garden with fountains and a water reservoir fed by a water-wheel system that pumped river water through terracotta pipes. The complex, which blends Islamic, Persian, and Indian architectural traditions with distinctive Bengali adaptations, stands as the most significant surviving monument of the Mughal era in Bangladesh and is listed on the UNESCO World Heritage Tentative List, making it a vital cultural landmark and a popular destination for history enthusiasts and tourists visiting the old city.
