The Land Chronicle mentions the allocation of 10,000 crowns for conservation in the former Sobieski tenement house in the Lviv market square. Among other things, a sharp-arched vault dating back to the 15th century and a vault from the Renaissance were uncovered in the tenement (Source: "Ziemia. Tygodnik Krajoznawczy Ilustrowany', Warsaw 1910, no. 28, pp. 17-18, after: Wielkopolska Biblioteka Cyfrowa).

Restoration of the Sobieski tenement house in Lviv.

From the 15th century, from the original times of this commemorative tenement; in two other chambers, after cleaning, an ornamental Renaissance vault appeared. The works on the cleaning of these three chambers are to be completed by the end of June, as the management of the National Museum, located in this tenement house, wishes to arrange and open an armoury there on the anniversary of Grunwald, i.e. in mid-July, which currently consists of several hundred specimens from the 15th century.

Further reconstruction of the Royal House will take place once the necessary funds have been obtained. According to the cost estimate, the restoration of this precious historical jewel of Lviv to its former glory will require an amount of about 180,000 kor.
