9. Alexander Castle is one of the most amazing and renowned structure in Mymensingh District. It was built by Maharaja Suryo Kanta Acharya Chowdhury(মহারাজ সুর্যকান্ত আচার্য চৌধুরী) in 1879 in the memory of the 1st zilla magistrate of Mymensingh Mr. N .S Alexander at the time of Jubili festival. It covers an area of 27.155 acres.It is a nice small archaic building having two Greek statue at both sides of the front gate. Though the arms of those statues are currently broken, but still those looks great. The whole building is placed over a high plinth, probably to avoid the flood from the nearness river.
