Kamieniec Zabkowicki is known for the former Kamieniec Abbey, established in 1209 as an Augustinian college at the site of a former castle of Bretislaus II of Bohemia. In 1247 it became a filial monastery of the Cistercian Abbey. Secularized in 1810 by order of King Frederick William III of Prussia, the estates of Kameniec were acquired by Wilhelmine of Prussia, wife of King William I of the Netherlands. Between 1838 and 1873 their daughter Princess Marianne of the Netherlands and her husband Prince Albert of Prussia had a new palace built in a Neogothic style according to the plans of Karl Friedrich Schinkel. As a result of the 1945 Potsdam Conference, Kamenz was put under Polish administration. The Palace was plundered and set on fire by the Red Army. Since 1995 it has been partially restored. Kliczkow was founded as a border fortress by Duke Bolko I in 1297. In 1391, it fell into the hands of the Rechenberg family from Saxony, who held it for almost 300 years. The main building was built in 1585 in the Renaissance style. After several more changes of ownership, it came to John Christian, Count of Solms-Baruth in 1767. In 1810, an expansion of the castle begun in mixed styles: English Gothic architecture with Italian Renaissance and French mannerism. The castle survived the Second World War virtually unscathed, but the interior was looted by Soviet troops. After the fall of Communism, a commercial company from Wroclaw purchased the castle and developed it into a luxurious conference and recreation center that was opened in 1999.
