The Oselce Castle was built in the early Baroque style in 1680. It was built on the site of a medieval fortress, which was rebuilt in the Renaissance style. In 1707–1737, the castle was rebuilt by Giacomo Antonio de Maggi, and the castle chapel was added. In the basement of the castle chapel, there is a ceiling fresco of St.
John of Nepomuk and Czech patrons from the first half of the 18th century. The castle is surrounded by an English-style park. There is a large Baroque one-story granary in the park. Today, the castle houses the school. The parish Church of the Assumption of the Virgin Mary is the main landmark of the village of Kotouň. It was built by G. A. de Maggi in 1703–1705. It replaced an old church from 1475, destroyed by fire. The church complex is also formed by adjacent cemetery with a Baroque bell tower from 1696. Near the church, there is a valuable early Baroque building of the rectory, which dates from 1736. The Chapel of Saint Margaret is located on Markétin vrch hill. This Baroque chapel dates from 1691. ==References==
