By the end of the 18th century, London, Bristol, Birmingham, Manchester and Leeds were linked by inland navigation. Many miles of canals remain in London, most unknown to the passing motorist. British Waterways London is offering free after-school workshops for primary teachers, where they can learn more about this rich historical heritage, and where the future regeneration of the network can be explored. These will include a trip on Beauchamp, a purpose-built floating classroom with a permanent crew and teacher, and a visit to the only museum in the capital devoted to inland waterways. The workshops take place on March 12, 13, 14 and 19 and April 10.
