Riga Old Town (Vecrīga) is the historical center of Riga, Latvia, located on the east side of Daugava River. Vecrīga is famous for its old churches and cathedrals, such as Riga Cathedral and St. Peter's church.
Vecrīga is the original area of Riga and consists of the historic city limits before the city was greatly expanded over the years. In the old days, Vecrīga was protected by a surrounding wall except the side adjacent to the Daugava river bank. When the wall was torn down, the waters from Daugava filled the space creating Riga City Canal.
In the 1980s Vecrīga's streets were closed to traffic and only area residents and local delivery vehicles are allowed within Vecrīga's limits with special permits. Vecrīga is part of a UNESCO World Heritage Site listed as "Historic Centre of Riga".
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.
