Porvoo was first mentioned in documents in the early 14th century, and Porvoo was given city rights around 1380, even though according to some sources the city was founded in 1346. Porvoo is famed for its old town (Gamla Stan in Swedish), a dense medieval street pattern with predominantly wooden houses. The town was mainly destroyed by fire in 1760 and current buildings were built after that.
Today Porvoo old town is a pictoresque tourist attraction. Many of the boutiques and services are located on Jokikatu and Välikatu Streets and around the church, but it's also worth looking a bit further. In the sidestreets and lanes it's easy to take a step back in time and forget the modern world. The small idyllic parks and sleepy cobbled streets among the houses entice the visitors to linger and reflect on the past.
The Old Town came close to being demolished in the 19th century by a new urban plan for the city. The plan was cancelled due to a popular resistance headed by Count Louis Sparre.
The red-coloured wooden storage buildings on the riverside are a proposed UNESCO world heritage site. Already by the early 19th century the authorities understood the value of the old town, and so with the need for growth a plan was made for a 'new town' built adjacent to the old town, following a grid plan but with houses also built in wood.
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.
