Black Jack's Lock & Mill and the Grand Union Canal
Black Jack's Lock is one of the many working locks along the Grand Union Canal, and the Victorian mill which is named after it is still visible on an island between the two waterways. The Grand Union Canal has evolved continually over 200 years and its main line runs all the way from Brentford to Birmingham, although it has several arms to places such as Leicester and Northampton.
The canal has undergone many changes, unifications (as the name suggests) and modernisations in an effort to keep up with competition from the railways. Even today, plans have been drawn up to further extend the waterway which would involve the construction of the first new British canal for a century.
