The Church of St. Casimir is a Roman Catholic church in Vilnius' Old Town, close to the Vilnius' Town Hall. It is the first and the oldest baroque church in Vilnius, built in 1618.
The construction of the church began in 1604 in memory of the holy prince Saint Casimir. It was built by the Jesuits with funding by the Great Chancellor of the Grand Duchy of Lithuania Lew Sapieha, Voivode of Vilnius Mikołaj Krzysztof "the Orphan" Radziwiłł, and other nobles. It is traditionally assumed that the corner stone was pulled into the city by procession of 700 Vilniusites from the Antakalnis hills. The construction was finished in 1616, and the interior design completed in 1618.
