York is an historic ancient city. Founded by the Romans during their conquest of Southern Britain, it later became a centre for the Anglo-Saxon church, for the Vikings and for the Normans as a stronghold in Northern England. Much of that rich history remains visible today, with the Norman wall built on top of the earlier Roman defences. The wall still defines the modern city centre, which is compact and easily walkable, straddling either side of the River Ouse. Other major attractions include the historic York Minster, the Jorvik centre, the Railway Museum. All participants in the conference will have free access to the York Museum as well. Further away, Castle Howard is an imposing grand country house, famous for its appearance in TV and films, and the North York Moors and Yorkshire Dales are both within reach. The city also has a wide variety of pubs, restaurants and clubs.
