The picture was taken in Tamsui, near the outlet of the Tamsui River into the Taiwan Strait. The curve is an entrance to a boat, which I guess is a restaurant, in the Tamsui river bank. At that time, the entrance was closed, so I cannot enter the boat. Tamsui is a well known tourist destination in Taipei. Some interesting places in Tamsui are: Hongmao Castle (Fort San Domingo) (紅毛城, lit: Red Hair Castle), Tamsui Old Street and waterfront (淡水老街), Tamsui Ferry Pier, and Tamsui Fisherman’s Wharf (淡水漁人碼頭).
