Indiana Jones and the Great Circle: All Collectibles at Marshall College
Where to find every collectible and field note in the Marshall College location.
This door is a part of the Underground Boxing Ring discovery quest, which will reward the player with two new adventure books and a healthy amount of cash upon completion.

Find the Locked Door
To trigger the Underground Boxing Ring quest, head to the doorway between the Belvedere Courtyard and the Sistine Chapel and walk down the stairs. At the bottom of the stairs there will be a large wooden door that you’re able to interact with. Knock on the door, and you’ll be rejected by the bouncer, starting the quest.
Find the Blackshirt Uniform
You must now find the Blackshirt Uniform disguise, which is located in a small encampment on the south end of The Vatican. In order to reach this area, you must progress through the Main Story until after you have met Gina and used her binoculars.
Go into the Excavation Site and through the side of the Apostolic Palace. There is a zipline between the two patios, with a large gap underneath. This gap is where the uniform will be located (and guarded by three enemies). You can use your whip to climb out of the enemy area.

Enter the Underground Boxing Ring
Head back to the large door, and open your satchel to equip the Blackshirt Uniform as your disguise. When you knock on the door while wearing it, a cutscene will play and you’ll be allowed in.
Defeat All Opponents
Once inside, you’ll be invited to participate in the Boxing Ring. There are a total of three different enemies to defeat, each one larger than the last. We recommend bandaging up, as well as eating fruit and bread before each match. After defeating an enemy, the bouncer will provide you with a cash reward at the table near the front. There is another table where two adventure books can be purchased.
