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 Kalozha church of Saints Boris and Gleb is the oldest extant structure in Hrodna. It is the only surviving monument of ancient Black Ruthenian architecture, distinguished from other Orthodox churches by prolific use of polychrome faceted stones of blue, green or red tint which could be arranged to form crosses or other figures on the wall.
The church is a cross-domed building supported by six circular pillars. The outside is articulated with projecting pilasters, which have rounded corners, as does the building itself. The ante-nave contains the choir loft, accessed by a narrow gradatory in the western wall. Two other stairs were discovered in the walls of the side apses; their purpose is not clear. The floor is lined with ceramic tiles forming decorative patterns. The interior was lined with innumerable built-in pitchers, which usually serve in Eastern Orthodox churches as resonators but in this case were scored to produce decorative effects. For this reason, the central nave has never been painted.
The church was built before 1183 and survived intact, depicted in the 1840s by Michał Kulesza, until 1853, when the south wall collapsed, due to its perilous location on the high bank of the Neman. During restoration works, some fragments of 12th-century frescoes were discovered in the apses. Remains of four other churches in the same style, decorated with pitchers and coloured stones instead of frescoes, were discovered in Hrodna and Vaŭkavysk. They all date back to the turn of the 13th century, as do remains of the first stone palace in the Old Hrodna Castle.
In 2004, the church was included in the Tentative List of UNESCO"s World Heritage Sites.
