York Minster is "an imposing Gothic Anglican cathedral in York, Northern England," according to the Wikimapia  page for the map of the cathedral grounds. It was once a wooden church built in 627 A.D. on the ruins of the ancient Roman Fortress of Eboracum. 

The VRYork website offers a superb 360-degree panoramic view of the cathedral's interior, with an interactive map of the surrounding city.  One may also find photo slideshows and a summary of the many relics and treasures on display at the cathedral's Official Web Page, here.

From Wikipedia:

"York Minster is a cathedral in York, England and is one of the largest of its kind in Northern Europe. The minster is the seat of the Archbishop of York, the second-highest office of the Church of England and is the cathedral for the Diocese of York; it is run by a dean and chapter under the Dean of York. The formal title of York Minster is "The Cathedral and Metropolitical Church of St Peter in York".

"The title minster is attributed to churches established in the Anglo-Saxon period as missionary teaching churches, and serves now as an honorific title.

"The minster has a very wide Decorated Gothic nave and chapter house, a Perpendicular Gothic choir and east end and Early English north and south transepts. The nave contains the West Window, constructed in 1338, and over the Lady Chapel in the east end is the Great East Window, (finished in 1408), the largest expanse of medieval stained glass in the world. In the north transept is the Five Sisters Window, each lancet being over 16 metres (52 ft) high. The south transept contains a famous rose window.
