Doclea (also Dioclea) was a Roman city, the seat of the Late Roman province of Praevalitana, and an Archbishopric, which is now a Latin Catholic titular see.
The Romanized Illyrian tribe known as Docleatae that inhabited the area derived their name from the city. It was the largest settlement of the Docleatae, founded in the first decade of the 1st century AD. Doclea was built to conform to the terrain. It was a large town with 8–10,000 inhabitants. The surrounding area had a relatively high population density within a radius of 10 km due to the city's geographical position, a favorable climate, positive economic conditions and defensive site that were of great importance at that time.
After the administrative division of the Roman Empire in 297, Doclea became the capital of the newly established Roman province of Praevalitana.
In the 4th and the 5th centuries, it was taken by the barbarian tribes and went into decline. At the beginning of the 5th century, it was attacked by the Germanic Visigoths. A severe earthquake destroyed it in 518. The South Slavs proceeded to rebuild the settlement in the 7th century. The historical ruins of the town can be seen today.
Circa 400, the city became the seat of an archdiocese, apparently Metropolitan as capital of a Late Roman province Dalmatia Superior. It was suppressed in 927. From 1034 till circa 1100, it was nominally united (as a title) with the then still Metropolitan Archdiocese of Bar (Antivari), also in modern Montenegro.References:
Hluboká Castle (Schloss Frauenberg) is considered one of the most beautiful castles in the Czech Republic. In the second half of the 13th century, a Gothic castle was built at the site. During its history, the castle was rebuilt several times. It was first expanded during the Renaissance period, then rebuilt into a Baroque castle at the order of Adam Franz von Schwarzenberg in the beginning of the 18th century. It reached its current appearance during the 19th century, when Johann Adolf II von Schwarzenberg ordered the reconstruction of the castle in the romantic style of England's Windsor Castle.
The Schwarzenbergs lived in Hluboká until the end of 1939, when the last owner (Adolph Schwarzenberg) emigrated overseas to escape from the Nazis. The Schwarzenbergs lost all of their Czech property through a special legislative Act, the Lex Schwarzenberg, in 1947.
The original royal castle of Přemysl Otakar II from the second half of the 13th century was rebuilt at the end of the 16th century by the Lords of Hradec. It received its present appearance under Count Jan Adam of Schwarzenberg. According to the English Windsor example, architects Franz Beer and F. Deworetzky built a Romantic Neo-Gothic chateau, surrounded by a 1.9 square kilometres English park here in the years 1841 to 1871. In 1940, the castle was seized from the last owner, Adolph Schwarzenberg by the Gestapo and confiscated by the government of Czechoslovakia after the end of World War II. The castle is open to public. There is a winter garden and riding-hall where the Southern Bohemian gallery exhibitions have been housed since 1956.
