The beauty of the Elan Valley is undeniable and the Foel Tower is one of its highlights. The 52m structure is situated above the Frankley Reservoir in Birmingham and the aqueduct that joins them means that water can flow solely by gravity – an amazing engineering feat even by today’s standards. The tower and the outstanding countryside that surrounds it is a wonderful introduction for visitors to the Elan Valley and will entice them to venture further into the valley to discover its network of dams.
