Niederruppersdorf Castle is an 18th-century moated castle built on the ruins of a medieval moated castle that had burned down. In the same year, the present castle was erected on the site by Johann Heinrich Gottlob von Nostitz, canon and senior member of the Prince-Bishopric of Meissen, according to plans by Johann Andreas Hünigen. Architecturally, it is a massive, simple structure built on high, square foundations with buttresses supporting the cellar. The two residential floors are crowned by a three-story mansard roof. The portal on the south side is reached via a double-arched bridge over the former moat and is decorated with the coats of arms of the Nostitz and Minckwitz families. Inside, the ceilings of the upstairs hall and the fireplaces are adorned with Rococo ornaments.

The secular and aristocratic Protestant Joachimstein Monastery in Radmeritz was once considered the most beautiful castle in Upper Lusatia. It is located near Radomierzyce in Poland, directly adjacent to the Hagenwerder border crossing. It was founded as a nunnery on an artificial island at the confluence of the Witka and Neisse rivers. This palace could be a unique attraction in Poland. It was once visited by European governments (from Augustus II the Strong, King of Poland and Saxony, through Frederick II the Great, King of Prussia, to Paul von Hindenburg, President of the Weimar Republic). The palace complex is situated on the water, and the palace itself has 12 chimneys, 52 large doors, and 365 windows. After the death of the palace's last owner in 2003, renovation work on the building, which had been in ruins since the 2nd century, practically ceased, and today, viewing the palace complex from the outside is the only way to experience this architectural gem. During World War II, the Nazis resided here. In 1944, they built an armored room – a vault for the documents of the Reich Main Security Office. After the war, Polish soldiers under the command of Piotr Jaroszewicz (later Prime Minister of the Polish People's Republic) arrived at the palace. Jaroszewicz discovered armored rooms containing secret Third Reich files. These contained, among other things, information about important figures collaborating with Nazi Germany. The case had a tragic ending. In 1992, Jaroszewicz and his wife were brutally murdered. He was tortured before his death, and she was shot. The Prime Minister's feet were nailed to the floor and tied, leaving only his right hand free – hence the presumption that he was forced to sign some documents. Nothing was stolen from his villa – only his office was ransacked, as if the murderers were searching for documents. The latest findings link the case to the files from Radomierzyce. Significantly, other people who visited the palace in 1945 were also murdered – Jaroszewicz's associates, Tadeusz Steć and Jerzy Fonkowicz. Steć was also tortured. It's also worth mentioning what happened to the palace after the war. Of course, it was plundered, a fact contributed to by the Turów mine. Historic sculptures were taken from there to a recreation center for mine workers. Stone lion statues were placed near the Bogatynia reservoir, from where they disappeared, and their whereabouts remain unknown to this day.

Kloster St. Marienthal is Germany's oldest continuously existing Cistercian women's monastery, founded in 1234 by Queen Kunigunde of Bohemia. It has been rebuilt multiple times, notably in Baroque style after a fire in 1683. The nuns have lived and worked here following the Rule of Saint Benedict for centuries, and in 1992, they established an international meeting center, repurposing historic economic buildings.
