Recent excavations have shown that after the fall of the Roman empire around the 9th century the friars who controlled the Colosseum rented out the space to ordinary citizens which made the Colosseum a ‘condo’. Stables, workshops and residences all were a part of this new use for the Colosseum. It appears the Colosseum was used like this until 1349 when an earthquake made the building architecturally unsound.
