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 Temple of Portunus or Temple of Fortuna Virilis ('manly fortune') is one of the best preserved of all Roman temples. Its dedication remains unclear, as ancient sources mention several temples in this area of Rome, without saying enough to make it clear which this is.
The temple was originally built in the third or fourth century BC but was rebuilt between 120-80 BC, the rectangular building consists of a tetrastyle portico and cella, raised on a high podium reached by a flight of steps, which it retains.
The temple owes its state of preservation to its being converted for use as a church in 872 and rededicated to Santa Maria Egyziaca (Saint Mary of Egypt). Its Ionic order has been much admired, drawn and engraved and copied since the 16th century. The original coating of stucco over its tufa and travertine construction has been lost.
