The Vastseliina Castle was a castle of the Livonian Order, Bishopric of Dorpat. It was constructed in 1342 by the Landmeister Burkhard von Dreileben as part of the border fortifications of Old Livonia against Novgorod, Pskov and later Moscow. In the Middle Ages, Vastseliina Castle was well known in the Catholic world as a popular destination for pilgrims. They worshipped the holy cross in the castle chapel and a visit to the chapel gave them sanctification for 40 days – it was first validated by Pope Innocentius VI in 1354.
The castle met its end during the Great Northern War when it was demolished by Russian troops (1702). Today the ruins are open to the public.

Spišskà Kapitula, a unique fortified ecclesiastical ensemble, began as a small fortified settlement overlooking Spišské Podhradie in the 12th century. It was the site of the residence of the Provost of the castle, in the no longer extant St Martin"s monastery, and later became a capitulary. This was destroyed in by Tatars in 1241-1243, but the pilgrim"s chapel, in rotunda form and dedicated to the Virgin, survived until the 18th century and the monastery until the 15th century.
The complex of buildings there is based on the Cathedral of St Martin, where building began in 1285 as a three-aisled Romanesque basilica with a chancel at the west end and a double spire. It owes its present form to successive remodellings and additions in the Gothic, Renaissance and Baroque styles.
The Provost's residence was completed in 1281 and further religious buildings were added. Frequent raids by marauding Bulgars and others led to its being fortified in the 14th century. The cathedral was rebuilt in the later 14th century. In 1776 it became the residence of the Bishop and four years later a seminary was established. In 1819 the first teacher training centre in Hungary was founded there.
The Bishop's Palace is largely Baroque, with some excellent interior decorations, like many of the religious buildings in the group. The oval ground plan of the centre of the town is due to its having been fortified in the 14th century. The various religious buildings had defensive functions in this early period. New monastery buildings were erected when the provost"s residence was rebuilt and the whole area fortified. The earlier central fortifications were removed in the 18th century.
Spišské Kapitula is part of the UNESCO World Heritage site Levoča, Spiš Castle and the associated cultural monuments.
