The Oldřich Oak, also known as the Prince Oldřich Oak, is a Pedunculate Oak (Quercus robur) tree located in the market town of Peruc. It is estimated to be about 1,000 years old. The tree has a height of 30 m and a trunk circumference of 810 cm.
The tree derives its name from a legend, set in the 11th century, involving Oldřich of Bohemia and Božena, the mother of his only son. According to the legend, Oldřich set out on a hunt and travelled to Peruc. There, he spied a beautiful peasant girl, Božena, by a well (known today as Božena's spring) and was immediately entranced by her. Oldřich abandoned his hunt and took Božena back to Prague, and she eventually gave birth to his son Bretislaus. In the legend, Oldřich's first meeting with Božena took place in sight of the Oldřich Oak.
The Oldřich Oak is mentioned in the Chronicle of Dalimil.
References:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
