Peterborough is mid-way between the East Anglian coast and the Midlands and has excellent road and rail connections both north-south and east-west. The city is 90 miles from London, five miles from the A1, and less than 20 miles from the A14, which links the east coast ports of Felixstowe and Harwich with the Midlands. London is just 50 minutes away by train - the city is on the East Coast main rail line which links London with Leeds, York, Newcastle, Edinburgh and Glasgow. An west-east rail line links Peterborough with Norwich, Great Yarmouth, Leicester, Birmingham and even further beyond that. Peterborough is a city rich in history - just to the east, archaeologists have discovered a 3,000-year-old settlement at Flag Fen. Later, the Romans established a large industrial city to the west of Peterborough, to exploit the reserves of clay. The city's Norman cathedral was founded in 650AD, and the most early part of the present building dates from 1118AD. From medieval times to the start of the industrial revolution, Peterborough was a moderately sized market town on the edge of the Fens. Its real growth started in the mid-19th century, with the arrival of the railways. Peterborough soon became a major railway junction and attracted a number of big industrial companies.
