Foundry (Earth-1: Pre-Crisis)

The Foundry, also known as the Lair and Arrowcave, was the base of operations of Team Arrow from 2012 to 2015. It is located in the basement of Queen Industrial Inc., later known as Verdant.

Original design
After Oliver returned after 5 years, he went to the Queen Industrial Inc. He later set up the equipments and his arsenal in the building. Later, he realized he needed a disguise for the lair and opened a nightclub known as Verdant. When Felicity Smoak joined the team, she upgraded the computer system and became the mission control of the team.

Second design
After The Undertaking, Felicity upgraded the lair for the second time and redesigned the entire lair. She added a mannequin to hold Oliver's suit and his bow. She also installed a better computer system for the lair.

When Roy joined the team and latter became Arsenal, another mannequin was added for his suit and bow.

Compromised
In late 2015, Lance raided the lair and revealing the secrecy of the location. As the secret is out and the base is no longer functional, the team moved the equipments away and relocated to Lair 2.0.
