U tekstu se razmatraju prva dva stoljeća povijesti Novog Mjesta, kapele i njezinih pokrovitelja, od utemeljenja do obnove početkom 16. stoljeća (1302. – 1502.). Analiziraju se geodetskim mjerenjima utvrđeni položaji uzdužnih osi u kapeli (os svetišta i os broda) i pomoću njihovih azimuta datira se njezino utemeljenje. Sveto usmjerenje kapele i njezin izvorni titular dovode do zaključka da je crkva utemeljena 1302. i posvećena dominikanskom redovniku sv. Petru mučeniku. Kapela sv. Petra utemeljena je u doba Ladislava Rakovečkog koji je sjeverozapadni zid broda dao oslikati prizorima iz ciklusa Legende o sv. Ladislavu, posvećenih njegovu zaštitniku. Pored njih u kapeli je fragmentarno sačuvano i više slojeva zidnih slika iz 14., 15. i 16. stoljeća, među kojima su najvrjedniji scene Majke milosrđa i Jeseova stabla na trijumfalnom luku, te Sveto lice iz Luccae i apostoli na zidovima svetišta.; The paper elaborates on the first two centuries of Novo Mjesto's history, the chapel and its patrons dating from the chapel’s establishment to the restauration at the beginning of the 16th century (1302 – 1502). The time of the chapel's establishment is determined on basis of longitudinal axis azimuths estimated on basis of geodesic measurements (from the shrine to the nave axis). The chapel's sacred orientation and its original titular lead to the conclusion that the church had been established in 1302 and dedicated to the Dominican friar St Peter Martyr. St Peter's chapel was established in the period of Ladislav Rakovečki who had the north-west nave wall painted with scenes from the Legende o sv. Ladislavu (Legends about St Ladislav), dedicated to his protector. There are also several layers of mural paintings from the 14th, 15th and 16th centuries preserved in fragments, among which the most valuable are the scenes Mother of Mercy and Tree of Jesse on the triumphal arch, and Holy Face of Lucca and apostles on the shrine walls.
