The epitaph plaque, made of black marble, commemorates Franciszek Ksawery Pniewko-Ciesielski – the parish priest of the parish in Sucha, in the years 1836-1873. During his life, father Ciesielski gathered a rich collection of books, purchased by Count Aleksander Branicki who transferred them to the castle in Sucha.
