Square Tower.

Another legacy of the White Rajah of Sarawak, the Square Tower was built in 1879 as a detention centre during the British time, converted into a fortress and then a dance hall. It was originally built as an annex to Fort Margherita. Fort Margherita which was erected the same year is on the opposite bank of the river. The Square Tower's architecture reflects the Victorian era’s fascination with native culture. The Square Tower is located at the west end of the Kuching Waterfront, on the Sarawak River, across from the Astana. Its is only about 1.5 blocks away from the Round Tower. It also marks one end of the popular Kuching Waterfront.
