Souvan House (Slovene: Souvanova hiša), is the highest building at Town Square in Ljubljana, the capital of Slovenia. It stands near the Ljubljana Town Hall. The building was originally erected in the 17th century and renovated upon the plans by Francesco Coconi in 1829. Its façade from the early 19th-century is one of the highest-quality examples of Biedermeier architecture in the city. It is decorated with Coconi's reliefs representing trade, art and agriculture.
