Britain's Lost Masterpieces Season 2

Pollok House is a country house right in the middle of a Glasgow city park, bordered on one side by the M77 and on the other side by the south side of Glasgow. It is owned by Glasgow City Council and looked after by the National Trust for Scotland.

Along with a hippo skeleton, a stuffed hedgehog and a log boat, Derby Museum has the best collection of Joseph Wright of Derby paintings in the world. Wright of Derby is one of the greatest English artists who ever lived.

Carmarthenshire County Museum is a slice of history in itself. The building that houses it has been in continuous use since the 13th century. Once a bishop's palace, it was where the Bible was first translated into Welsh.

Hospitalfield House in the fishing town of Arbroath on Scotland's east coast is a Victorian treasure trove. The couple who owned this great house back in the 19th century were obsessed with the decorative arts.
