Arrowcave

The Arrowcave is the headquarters for Oliver Queen and his team that houses his equipment and costume for his heroic persona, The Arrow, now Green Arrow. The base now also holds the gear for the Black Canary, Speedy, and Spartan.

What was to become the base of operations for Oliver, was originally one of the factories of the Queen Consolidated, located in the Glades. After the great increase of crime in the Glades, the factory was closed, and there was left in the open structure. The bottom of it was a big empty space that served as a conduit pipe. After the Alpha-Omega bio-attack on Starling and the SCPD's discovery of the base (courtesy of Ra's al Ghul), the team relocated to Oliver's secondary base located underneath Palmer Technologies. After Jeremy Tell infiltrated the base, Oliver decided to once again relocate the base, claiming that it would be a "surprise", and with help from Cisco Ramon and S.T.A.R. Labs, it was located underneath his mayoral campaign headquarters.

Used by Oliver Queen, John Diggle, Felicity Smoak, Thea Queen, and Laurel Lance, it is sometimes referred to as The Foundry or The Lair.
