Secret Scotland with Susan Calman (C5, 8pm)

CALMAN is back for a third series and her latest journey begins with a hunt for secrets in the former industrial powerhouse of Falkirk.

A few miles from Falkirk, Calman visits giant Georgian pineapple, and ventures into Midlothian to explore a royal hideaway filled with stories of passion, betrayal and daredevil courage.

Atlantic: A Year in the Wild

(C5, 9pm)

AS winter draws to a close, the Atlantic springs back to life. Temperatures rise, days lengthen and food is plentiful again. However, spring in the north is short, the animals only have a few months to find food, a mate and start a family – all the while avoiding predators. Around the British and Irish coast, thousands of gannets must find a place to nest before they can raise a family. Meanwhile, killer whales leave Iceland and head to the Shetland Isles, where they hunt harbour seal pups.

The Romantics and Us with Simon Schama (BBC2, 9pm)

THE historian recounts the story of how the Romantics, fuelled by the failures of the French Revolution and horrors of the Industrial Revolution, retreated from the tragic uproar of public life to take a journey into their own minds. Here, long before Freud and Jung and the modern psychological revolution, they discovered the subconscious – something that would have a profound effect on the modern world. Contributors include Tobias Menzies, Peter Doherty, Piotr Anderszewski

and David Attenborough.
