Karlstein was first mentioned in 1112 as "Chadelstain." As a fiefdom, Karlstein belonged to the respective territorial princes, who granted this rule to knightly families, although no continuous dynasty established itself here. Since the castle was never owned by a single family for an extended period, it was continually rebuilt and expanded. Practically nothing remains of the original castle. In the following centuries, the border region was repeatedly raided by enemy armies (Ottokar, Hussites, Matthias Corvinus). After the suppression of the Peasants' Revolt in 1597, the leader, Andreas Schrembser, was presumably imprisoned in Karlstein Castle. In 1645, the Swedes besieged Karlstein Castle in vain. In 1663, it served as a refuge during the Turkish threat. In 1914, an internment camp was established in the castle, despite it being uninhabitable. The Montenegrin General Staff was also imprisoned there. After the war, the Hungarian communist leader Béla Kun was interned here. Later, the castle was used as a youth hostel, and in the 1960s, it also served as a guesthouse. The castle is now privately owned and no longer open to the public.

Castle visits are possible with a guide, but only on weekends. Getting there is the easiest when approaching the Raabs an der Thaya from the south. Road uphills from the town centre is very steep, so prepare for pushing the bike.

The Raabs Borderland Museum was founded in 1984 by the town of Raabs under the then City Councillor for Culture Othmar Knapp. The museum building was built by the Raabs Raiffeisenkasse. Under the motto "6,000 years of farming on the Thaya", the Neolithic stone axes found in the town area, medieval archaeological finds, remaining inventory items from Raabs Castle and various agricultural and forestry equipment are on display. In 1998, the museum was redesigned. In view of the sharp increase in archaeological finds in the area, a room was dedicated to "history from the ground". It was set up by Dr. Kurt Bors, who has been working in this area since 1987 on archaeological surveys and the localization of lost medieval sites. The second exhibition theme chosen for the anniversary in 2000 was "900 years of Raabs Castle and Market" and is dedicated to the historical development of the market up until it was declared a town in 1926. Opening hours: Mon-Thurs: 8 a.m. to 12 p.m. and 1 p.m. to 4 p.m., Fri: 8 a.m. to 1 p.m. and by telephone arrangement

The Renaissance Schwarzenau Castle was first mentioned - as a castle at that time - in 1150. It was converted into today's castle in the 16th century. During the Second World War it was used as a refugee center and occupied by the Soviets. During these years, the once magnificent building was badly damaged. From 1991 the castle - again privately owned - underwent extensive renovations. Today the complex impresses with a park and pond as well as valuable decorated outbuildings such as a tavern and chapel. The latter is considered a popular wedding location.

Schwarzenau Castle is a Renaissance castle surrounded by a park. Swarcenawe Castle, which originally stood here, was first mentioned in documents in 1150. The builder is the Pilgrim von Schwarzenau, mentioned in 1197, a follower of Hadmar II von Kuenring. His castle was a moated castle with four towers to protect the old Horn - Schrems - Gmünd road. Around 1580 and 1592, the castle was expanded into a Renaissance moated castle using existing parts. After the state treaty, the castle came into private hands and was restored. From 1991 it was again open to the public for exhibitions. In 2019 the palace complex was acquired by the Bulgarian Monbat Group.
