From the historical and architectural perspective, this is an interesting monument to urban construction between the 17th and 19th centuries. Old Liepāja is in the area of the old market and Kuršu Square, where merchants sold their wares beginning in the 1560s. Until 1792, Kuršu Square was also where punishments were implemented. The current Pētertirgus pavilion was installed alongside the square in 1910. A map shows that the network of streets has partly preserved the chaos of street planning that was typical in Medieval towns.
