The capital city Dhaka predominantly was a city of the Mughals. In hundred years of their vigorous rule successive Governors and princely Viceroys who ruled the province, adorned it with many noble monuments in the shape of magnificent palaces, mosques, tombs, fortifications and 'Katras' often surrounded with beautifully laid out gardens and pavilions. Among these, few have survived the ravages of time, aggressive tropical climate of the land and vandal hands of man.
But the finest specimen of this period is the Aurangabad Fort, commonly known as Lalbagh Fort. Which. Indeed represents the unfulfilled dream of a Mughal Prince. It occupies the south western part of the old city, overlooking the Buriganga on whose northern bank it stands as a silent sentinel of the old city. Rectangular in plan, it encloses an area of 1082' by 800' and in addition to its graceful lofty gateways on south-east and north-east corners and a subsidiary small unpretentious gateway on north, it also contains within its fortified perimeter a number of splendid monuments, surrounded by attractive garden. These are a small 3-domed mosque, the mausoleum of Bibi Pari the reputed daughter of Nawab Shaista Khan and the Hammam and Audience Hall of the Governor. The main purpose of this fort was to provide a defensive enclosure of the palatial edifices of the interior and as such was a type of palace- fortress rather than a siege fort.
