[2] The marketplace features a Ratusz town hall built between 1799 and 1804, which is now home to the Jarocin Regional Museum.

[3] The lordship of Jarocin was first mentioned in a 1257 deed issued by Duke Bolesław the Pious of Greater Poland.

The town was conveniently located at the intersection of the trade routes from Wrocław to Toruń and from Poznań to Kalisz.

The town was annexed by Nazi Germany in 1939 during World War II and administered within the newly formed province Reichsgau Wartheland as part of the district or county (kreis) of Jarotschin.

[9] Following the arrival of the Red Army and the end of the war in 1945, Jarocin was restored to Poland with however, a Soviet-installed communist regime that stayed in power until the Fall of Communism in the 1980s.

Main landmarks and points of interest include the old Radoliński Palace with an adjacent park, the Polish Rock Granary, a museum dedicated to Polish rock music, the Rynek (Market Square) filled with historic architecture, including the town hall, which also houses the historic museum, and the St. Martin's Church, and several Greater Poland Uprising memorials.
