David is off soon to his Derbyshire home's twin-town of Sindlefingen in Germany where there are a couple of decent towers and he hopes to meet there Guenther Bosch, the dedicated enthusiast behind the Baden Wurtemburg water towers website.
As said here before, BWTAS is British in name but not British in outlook. We exist for people in Britain who are interested in water towers. Many German towers were built by illustrious Britons such as William Lindley.
It would be great to locate some examples in continental Europe of his work.
