Bansuiso is a large villa, built in the style of a 19th century Gothic French château. The Earl Sadakoto Hisamatsu, a descendant of the Matsuyama clan, built it in 1922 as a second home. Having lived in France, Hisamatsu wanted to impress with Western style, and he hired architect Shichirō Giko to achieve it. The villa was a social mecca for the elite of that time, including the Imperial family. Today, exhibitions of the Museum of Art Ehime and concerts are held here.

Built on the land occupied earlier by the Corpus Christi hospital, one of the city's medieval hospitals. In 1558 the city exchanged plots with Archishop Esteban Almeyda and the hospital was relocated to the Parish of Santiago. The building may have started in the 16th Century, soon after the establishment of the Orihuela Bishopric. It underwent profound changes in the 18th Century under the reigns of Bishops José Flores Ososrio and Pedro Albornoa Tapia. In the mid-20th century, it lost its original functions, was restored at the beginning of the 21st Century and is currently home to the Diocese Museum of Sacred Art. At the back, facing the river, there is a gallery with semi-circular arches. Inside, another striking feature is the cloister with heraldic decoration, the main staircase of Alicante marble and the dome built on an octagonal base, with exterior cobalt blue glazed tiles.

Compact in size compared to some other nature reserves in The Gambia, Abuko is a convenient half-hour drive away from town. The nature reserve offers ample opportunities for bird-watching and interacting with resident monkeys. Skip the on-site zoo if seeing caged animals upsets you.
