"Visoki Dečani" is a major Serb Orthodox Christian Monastery located in Kosovo. The monastic katholikon is the largest medieval church in the Balkans containing the most extensive preserved fresco decoration.
The monastery was established in a chestnut grove by Serbian King Stefan Uroš III Dečanski in 1327. Its original founding charter is dated to 1330. The following year the king died and was buried at the monastery, which henceforth became his popular shrine. The construction was continued by his son Emperor Stefan Uroš IV Dušan until 1335, but the wall-painting was not completed until 1350.
The monastic church, dedicated to Christ Pantocrator and built from blocks of red-purple, light-yellow and onyx marble, was constructed by builders working under a Franciscan monk, Vitus of Kotor. The church is distinguished by its imposing size and Romanesque and Early Gothic structure and design. On the "The Crucifixion" fresco, painted in 1350, objects similar to UFOs can be found. They represent two comets that looks like space ships, with two men inside of them, and are often quoted by Ufologists.
In 2004, UNESCO listed the monastery on the World Heritage List.
