'The Man Engine' is the largest mechanical puppet ever constructed in Britain and continued a five day tour of Wales in Tredegar.
Thousands came to see the Man Engine come to life as part of a celebration of the history of coal and iron in the country.

The Man Engine started its Welsh tour with a visit to Big Pit in Blaenavon on Sunday.
It will also appear in Merthyr Tydfil, Pontypridd and Swansea.
