One of the finest beauty spots of the state, Nirmahal is situated 53 Kms from Agartala. The palace is so called as it is surrounded on all sides by a big lake called Rudra Sagar. The scenic beauty of the lake attracted Maharaja Bir Bikram Kishor manikya (1927-47) so much that he built a spectacular palace at the center of the lake itself named it as Nirmahal (or palace in water).
