One of the finest specimen of Mughals 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 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 seize-fort.
