Seems quite underground on tonight's episode:

Bettany Hughes' Treasures of the World
Gibraltar
Season 1 Episode 3/5

The historian explores Gibraltar, encountering the world's first evidence of Neanderthal art, and handles the first report of Admiral Nelson's death in the Gibraltar Chronicle. She also explores the colourful natural formations of the underground pleasure gardens, and discovers where Victorian officers left messages carved into cave walls
