[2] The conventions, which were held here in the 14th century gave the city greater importance in the Kingdom of Poland and according to contemporary chronicler Jan of Czarnków, Casimir III the Great ordered a residence to be built here, which was accomplished in 1347.
Therefore, the court architect of King Sigismund I the Old, Benedykt Sandomierski erected a new residence, which was completed in 1519.
[4] The new residence was built in the Renaissance style in the shape of a residential tower on a square measuring 18 × 20 m (19.68 × 21.87 yd).
in 1869 the Russian Governor of Piotrków undertook a restoration to convert the former royal residence into a garrison Orthodox church.
[1] After the war the Regional Conservator recommended rebuilding the castle by the state before Warszycki's reconstruction, restoring its Renaissance features.
