The Town Hall is actually a whole quarter. Its oldest building, the merchant's house, was built in 1797. In 1806 it served as an accommodation for the Russian Czar Alexander I during his visit to Pärnu. Legend has, that in 1819, on the command of the Czar, the merchant's house was turned into the house of the commandant of the town.
Since 1839, the building was used as Town Hall. In 1911 it acquired an Art Nouveau style annex contained premises of the city council. As of year 2009, the Town Hall accommodated the Visitor Centre of Pärnu. Nikolai street is named after the St. Nicholas Church that used to be located here and was destroyed in World War II. A memorial stone has been placed opposite the Town Hall under the oak trees which are the only remains of the church yard. The chapel of St. Nicholas Church was home for a well known pilgrimage object, the Black Cross. The Black Cross is also depicted on the coat of arms of Pärnu.

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.
