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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
