Built during the 14th and 15th centuries to ward off Scottish raiders, Newcastle's ancient city walls are a proud testament to the rich history of the city.
And the perfect place to have sex too, apparently.
This couple were snapped, er, hard at it by workers in the nearby WhatCulture offices, last week.
"Congratulations to the happy couple who just had sex on top of the Newcastle city wall. Rumbled," tweeted Simon Gallagher.
The sentiment was apparently echoed, with 1,106 retweets following quickly afterwards. And they say romance is dead.
