In 1826, Anglesey was connected to the rest of Wales by the construction of the Menai Suspension Bridge by Thomas Telford, and connected with London in 1850 with the building of the Britannia Bridge and the busy North Wales Coast railway line, which connected the rest of Great Britain to the ferry port of Holyhead. The old village, known as 'Pentre Uchaf' ("upper village") was joined by new development around the railway station, which became known as 'Pentre Isaf', the "lower village".
