Our Castlefield is the official website of the Castlefield Forum charity. Castlefield is the oldest part of Manchester, shaped by its Roman origins, the world’s first passenger railway, and some of the earliest canals of the Industrial Revolution. It is a place where history, community and city life meet. Today, Castlefield remains a distinctive and vibrant area, rich in heritage and character. It is a remarkable place to visit, live and work.
