Yesterday I watched a video about the world's shortest international border and found out about the rock fortresses of Spanish Morocco. Peñón de Alhucemas is built atop one of the three Alhucemas Islands. Peñón de Vélez de la Gomera used to be an island, now an connected by a short sandy beach is home to the shortest international border. Both are still occupied by small garrisons of Spanish forces.
I like that they could be support a group of people and are still close enough (1hr) from a city for scavenging.
