The Aleksa Votive Chapel

The small and modest building built near the village of Tarnów was designed by Marta and Lech Rowiński, as a wooden structure in a form of chapel with small bell tower. Three windowless walls are fully covered by wooden elements and the fourth wall is made entirely of glass. The structure is usually called a chapel or church, but it is incorrect, as stated in a letter by local Catholic bishop of diocese of Siedlce in 2020, as it has never been consecrated. This timber chapel-like building received a measure of international acclaim by being shortlisted for 2011 EU Prize for Contemporary Architecture - the Mies van der Rohe Award. Locally, it was honored by getting into top 5 candidates list for annual architecture award of Polityka magazine in 2011.
