The Arrow Cave is the main base and headquarters for Oliver Queen and his Team of John Diggle and Felicity Smoak who help in his vigilante work as Green Arrow. The base is located in Starling City in the part of the city known as The Glades underneath an old Queen Consolidated Factory. The old factory was later turned into Oliver Queen's nightclub known as Verdant which helped hide his actives as Green Arrow and hide his base as well. Recently after The Event of The Undertaking the base received many improvements and upgrades from Felicity Smoak.
