Now, solve this: Question: When was the building Wytk lived in built? Passage:Sinka began his military career as a familiaris of his maternal uncle George Baksa. In this capacity, he participated in King Andrew's royal campaign against Albert of Austria in the summer of 1291. According to his uncle's donation letter from 1299, Sinka bravely fought under the city walls of Vienna. He seriously injured during these clashes, as Andrew's privilege charter from 1300 narrates. He remained in the service of the Baksas for the following years. According to two documents issued by later family members in 1314 and 1317, a certain "Bohemian potentate" Wytk, who resided in Sáros Castle (present-day Šariš in Slovakia), invaded George Baksa's seat Sóvár (today Solivar, a borough of Prešov in Slovakia) and seized its salt well. Sinka led a military unit and successfully recovered the estate, while captured Wytk and burned the Bohemian lord's nearby fort. The 1317 charter contradicts this and narrates that Sinka already prevented Wytk from occupying the salt well. Some historians considered that the events occurred sometime between 1301 and 1305, during the brief reign of Wenceslaus, who installed his Bohemian partisans to several castles in Northeast Hungary. For a number of reasons, however, historian Attila Zsoldos argued the events occurred still during the reign of Andrew III and put the date to sometime before July 1294. In that year, Andrew confiscated Tamási in Szepes County (today Spišské Tomášovce in Slovakia) from George Baksa and his brothers because of their "disloyalty", as they "ravaged the realm" and "captured and wounded" Wytk, the royal castellan of Sáros. Zsoldos identified the castellan with Wytk Ludány, who came from a kindred of Bohemian origin, as Simon of Kéza's Gesta Hunnorum et Hungarorum preserved. The historian suggested that Wytk unlawfully tried to extend his influence over Sóvár by abusing the power of his position, but George Baksa and his nephew Sinka successfully repulsed the attack. Andrew III, whose whole reign was characterized by the confrontations with the oligarchs, regarded this act as a treachery without consideration of all aspects.

Solution:
According to two documents issued by later family members in 1314 and 1317, a certain "Bohemian potentate" Wytk, who resided in Sáros Castle (present-day Šariš in Slovakia), invaded George Baksa's seat Sóvár (today Solivar, a borough of Prešov in Slovakia) and seized its salt well
