 Copernicus was reportedly buried in Frombork Cathedral, but archaeologists searched there in vain for centuries for his remains.Efforts to locate the remains in 1581, 1626, 1802, 1909, 1939 and 2004 came to nought.In 1973 Dr Jerzy Sikorski published the location of Copernicus' resting place in his book, including the photo of the Altar of Saint Wacław, today Altar of Saint Cross, with a subscription (English translation of Polish) "The remains of Mikołaj Kopernik rest unnamed next to this altar".
