The Royal Tenement House in Lviv was built for a merchant who came from Crete, Konstantin Koniakt in 1580. The architect was Peter Barbon, although some researchers consider the tenements to be a design by Pavel Roman. The Coniaktas gave the building to the Carmelites in 1623, and from them, in 1640, it was bought by Jakub and Teofila Sobieski. After their death, Jan III Sobieski became the owner of the tenement house. As the building became one of the monarch's residences, it was given the nickname "royal". It was furnished with special flats on the first floor, the decoration of which has been preserved to this day. In 2020, the Polonica Institute financed the renovation of the historic hallway located on the first floor of the building.
