Petr Parléř was a medieval master builder active in Prague during the reign of Charles IV. From 1356 he directed the construction of St Vitus Cathedral, where he continued the work of Matthias of Arras [1]. According to the cathedral's website, together with him he gave the Gothic cathedral a form that became part of national history [1].
St Vitus Cathedral
According to the Prague Castle Administration, Matthias of Arras and later Petr Parléř built the chancel with its ring of chapels, the Saint Wenceslas Chapel, the Zlatá brána and the lower part of the Great South Tower. Parléř began building the tower but did not finish it [2]. The work on the cathedral was interrupted by the Hussite Wars, during which Parléř's sons boarded up the unfinished structure with a wooden wall [1].
Charles Bridge and the Old Town Bridge Tower
According to the Monument Catalogue of the National Heritage Institute, after the foundation stone of Charles Bridge was laid in 1357, the construction was led by Petr Parléř, who was probably also the author of the design of the Old Town Bridge Tower. Its construction began around 1370 and was completed around 1400. The catalogue states that an inscription in the triforium of the cathedral from the years 1388 to 1392 names Parléř as the author of the bridge and the tower, which, according to it, is also confirmed by stylistic analysis [3]. Prague City Tourism states that the tower was built to a design by Petr Parléř [4].
