The unpreserved design of the ‘The Princess Ogińska Gate’ in Siedlce is discussed. Founded by Michał Fryderyk Czartoryski in 1773-76, it was a town gate while also serving as the belfry of St Stanislaus Parish Church. The Author traces certain analogies between its composition and the ancient gate from Spello (a locality in the Umbria region) whose drawing was included in Book III of Sebastian Serlio’s treatise. Pointing to certain similarities, the Author demonstrates that the design was most likely executed by Szymon Bogumił Zug.
