After the end of the First World War, the Latvians laid claim to Mažeikiai, but the dispute was settled by international arbitration. The struggle over the borders between Lithuania and Latvia lasted for four years.
The structure of the Bank of Lithuania resembles a tulip blossom. The interior of the bank is Art Deco. The former Orthodox Church houses the Merkelis Račkauskas Gymnasium. The architect Vytautas Landsbergis-Žemkalnis was the author of the modern Catholic Church, but his project did not make the residents of Mažeikiai happy. From the press of the time: “The assistant to the burgomaster took the heel of an old rubber shoe and made a seal which was almost the size of a glass. An inscription Mažeikiai Town Board was added and so began their work”. Today the administration of Mažeikiai City Municipality is located here. The former building of the Lithuanian Farmers’ Cooperative Lietūkis, although painted over in Soviet times, the inscription was still visible. Mažeikiai Tumas-Vaižgantas Primary School (now Vytautas Klova Music School) was known for its strict rules - pupils were compulsorily taken to the sauna once a week, and even had to sign declaring that they had really come.
