At the southern end of Roncesvalles Avenue, at the Sunnyside intersection of King, Queen, Queensway and Roncesvalles streets, two monuments are erected in memory of two events in Polish history. A large monument in memory of the massacre of Polish prisoners of war during World War II, and especially the mass graves of officers found in Katyn forest. Fresh wreaths are placed there regularly. Next to it is a memorial to thousands of Polish citizens deported to Siberian labour camps during the Second World War.
