Merthyr Tydvil
Merthyr Tydvil, a town in Glamorganshire, stands on the Taff, at the apex of a triangle of which Swansea and Cardiff are the points at the base. It is the centre of the South Wales iron and steel manufacture and of the Glamorganshire coalfield. The growth of the place dates entirely from the manufacturing era, and it has no buildings with any pretence to beauty, while its sanitary arrangements were for a long time far from perfect. The parliamentary borough, which was formed in 1867, includes Aberdare and other environs, and now returns two members.
