Shurdhah Island is located in the Vau i Dejës Reservoir, which is fed and drained by the river Drin.
Sarda was founded between the 6th and 7th centuries. The town was strategically located on the old road from the Adriatic Sea to Dardania and served as a resting point along the trade route. The settlement originally had a wall encircling the entire hill it was built on. Encircled on three sides by the Drin river, Sarda had 12 towers of various forms. Sarda seems to have been a modest settlement from its foundation to the 9th century when it saw rapid expansion. It gained its highest importance in the 12th century, when it was the seat of the joint bishop of Sapa and Sarda. Around 1100 a Diocese of Sarda was established on the island.
The island was the original settlement of the feudal Lekë Dukagjini patriarch, famous for the rules of the Kanun. It was ravaged by the Ottomans in 1491.
Today tourists can visit the ruins of the 11th-century medieval castle, which includes two rings of defensive walls and towers (some sadly submerged in the lake), the remains of a Byzantine church and other early medieval walls. The setting on the steep rocks rising from the lake is especially impressive. The island is accessible by tourist boat in summer from the Vau i Dejës dam or Rragam.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
