Papplewick Arms

The Papplewick Arms was a pub frequented by the Lady Ada Lovelace in 1852. It located in Nottinghamshire, near Newstead Abbey, where the Countess took up residence during daytime. She would escape at nights in order to engage in gambling here, together with a regular group of participants. Lovelace habitually sat in her "usual chair", and played cards with such folk as Ted, George and Charlie.

On the night following his arrival at Newstead Abbey, the Fourth Doctor followed Ada all the way to the Papplewick Arms, and joined her group as the fifth in their card game. (AUDIO: The Enchantress of Numbers)
