Hussain Sagar Lake is one of the largest man made lake situated at the confluence of Hyderabad, Secunderabad and Begumpet. It is a sprawling artificial lake that holds water perennially. Its uniqueness lies in the fact that it connects the twin cities of Hyderabad and Secunderabad. The lake was built in the year 1575 by Sultan Ibrahim Kutb Shah at a cost of about Rs. 2.5 lakhs. The lake was originally constructed to supply drinking water but it is not used as a drinking water source since 1930. The lake also protected the citizens staying in the low lying areas around the lake from floods
