The chance to travel through millions of years of history, step into mines over 200 years old and use the world's first underground inclined lift - all possible if a Black Country site is lucky enough to receive a £50m lottery grant.

Mines at Wren's Nest National Nature Reserve in Dudley are part of the bid for the Black Country Urban Park - a project competing against three others for the Big Lottery's Living Landmark Award.

The mines, formerly quarried for their limestone, stopped working in 1925 and the site was abandoned.
