The historic walled city of York is home to a community rich in history, ambition and achievement, and has seen countless visitors, pilgrims and merchants walk its winding medieval streets over the centuries. Having been a cultural hub and centre of trade and commerce since before the Roman occupation of Britain, today York is considered one of the nation's most notable sites of architectural and historic interest. With the emergence of tourism in the late nineteenth century, the historic core of York became one of the city's major assets, and in 1968 it was designated a conservation area. Today York is noted, among other things, for its numerous churches and pubs. The city offers a wealth of historic attractions, of which York Minster is the most prominent, and a variety of cultural and sporting activities making it a popular tourist destination for millions. York the Postcard Collection is a fascinating collection of postcards that charts the city's evolution over the decades.
