 The capital of the province , Sira town , prospered most under Dilavar Khan and expanded in size to accommodate 50 @,@ 000 homes . ( See Map 10 . ) Palaces and public monuments of Sira became models for other future constructions ; both Haidar Ali 's palace in Bangalore and Tipu Sultan 's in Seringapatam , built during the period 1761 – 1799 of their rule , were modeled after Dilavar Khan 's palace in Sira . Likewise , according Rice 1908 , Bangalore 's Lal Bagh as well as Bangalore fort may have been designed after Sira 's Khan Bagh gardens and Sira fort respectively . Sira 's civil servants , however , could not be as readily reproduced ; after Tipu Sultan had succeeded his father as Sultan of Mysore in 1782 , he deported 12 @,@ 000 families , mainly of city officials , from Sira to Shahr Ganjam , a new capital he founded on Seringapatam island .
