Instead of mentioning a specific fort (Lalbag) you can write Bengali Castle is having fortification styles (wall texture) from Gauda/Lakhnauti (Old Capital of Bengal). It is also having the Bengali Chala Roof Style. But it is also having Chhatri Architecture Element borrowed from West India introduced into Bengal by the Mughals in late 17th Century. The wall also has some very little traces of lapis lazuli blue paint borrowed from Persia. Restructure the above sentences a little to increase readability. 
Maybe add information about this Omitted French Castle from LotW and Changed Bengali Wonder Trees from DoI into the Wiki as well into the DLC Trivia information.
