In 1638 St. Trinity Collegium (equivalent to today’s colleges) was founded in the city and logic, rhetoric, grammar, theology and fundamentals of sciences were taught there.
Unfortunatelly the old town-hall didn't survived the wars of XX century.
There is a legend about the royal love-story in Olyka, connected with the names of the last Polish king Stanislas II Augustus and a Polish princess that was the owners of the village of Chemeryn near Olyka. The mavsoleum of this princess stands in the old Olyka cemetary.
Even in the 20th century Olyka was prized by rich gentlemen. Thus, for the sake of its manors and against his parents’ will, Mykhailo Ferdinand Radziwill married beautiful Maria Benardaki on the eve of World War I. By the way, she had been Marcel Proust’s first love since childhood and the inspiration for Gilberta in his“In Search of Lost Time” novels.
The old city’s walls recall the awful fires of 1803 and 1823 and events of the war of 1812, when the palace was turned into a military hospital. Olyka, deprived of an attentive owner, began to decay and collapse. In 1838 the buildings of the college and seminary fell, and in 1870 the 17th century town hall, filled with invaluable town archives, burnt. But the Radziwills restored their family heirloom each time.
