Nanzen Temple is the head temple of the southern faction of the Rinzai school of Buddhism. Its biggest charm is the Suirokaku Aqueduct that sits quietly in the Japanese landscape. It was built in 1888 to carry water from Lake Biwa, and the original brick arch still remains inside the temple. If you get a chance to walk around the area, it's recommended that you head there from Keage Station on the subway. Once you pass through the brick tunnel, Nanzen Temple will welcome you.
