Henry VIII’s Lost Palace: Digging Up Britain, C5, 7pm

HELEN Skelton and Alex Langland’s latest journey takes them to Enfield, the site of Elsyng Palace, which is believed to have been one of Henry VIII’s favourite homes during the last decade of his life. For centuries its exact location was a mystery until, in the 1960s, new evidence revealed the area’s Tudor heritage. Now a new archaeological dig is taking place, offering clues to the palace’s architecture and splendour, as well as the way Henry lived. The presenters discover why Elsyng was so popular despite being a long ride from London – and it seems it was all down to a case of parental love. It’s enough to warm the cockles of your heart.

Plus, there is music from Snow Patrol and stand-up comedy from Kerry Godliman.

Black Lake, BBC4, 9pm

IN tonight’s double bill of the Swedish thriller, Minnie becomes even more convinced that there is a darkness dwelling over the island of Kallskar and that something terrible has taken place there. Whatever it is, she links it with the name Maja. Then, when Uno takes the group to visit a deserted cholera hospital on the other side of the island, Minnie is certain that she is getting close to the truth. However, it becomes apparent that there are powers working to prevent the secrets of the island from being exposed. Is it possible that the current disturbing events are related to what happened 160 years ago?

Through the Keyhole, STV, 9.30pm

LET’S face it, many of us love to see how the other half lives, especially if that other half is a celebrity. For more than 30 years Through the Keyhole has offered us an opportunity to play the nosy neighbour without ever moving from the safety of our own sofas. Over the decades the show has undergone various revamps, with the latest hosted by Keith Lemon, who is a far cry from original presenter David Frost. The sixth series began in December with a Christmas special; the rest of the run gets under way tonight, with Danny Dyer, Sally Phillips and Chris Kamara attempting to identify who are the owners of three mystery homes by their furniture, decor and personal items.
