The Head Post Office building was built in 1887-1889 on land that belonged to a Greek Catholic spiritual seminary (along Kopernyk st.), for which the area of the monastery orchard was diminished. The project looked like the typical post offices of Fr. Zetz, adapted to the city’s conditions and changed by Lviv architect Silvester Havryshkevych; undertaken by the union of architects Ludwig Ramult and Jozef Cybulski. In 1922 Chervins’kyi significantly reconstructed the building of the Main Post Office, ruined during the Polish-Ukrainian war. Slovak st. (until 1871- Palatsova), named in honour of one of the most famous Polish poets, joins the streets Kopernyk and 3^rd of May (Sichovi Striltsi st.).
