The Grand Court is a very large, open room in the Bryyo Cliffside.
Living up to its name, the Grand Court spans a huge area, like most rooms in its section of the Cliffside. Here, its main entrance leading from Grand Court Path overlooks the court. A level below that contains a Morph Ball tunnel covered by badly hinged panels that can easily be ripped off with the Grapple Lasso. On the lower level, there is a large inactive Mogenar-class War Golem in the center of the arena, which covers a Phazon pool. Two other chambers sit at the edges of the court: one leads to a small room, which can be blocked by a large stone structure in the case of hostile life-forms, and contains the Age of Science Bryyo Data entry behind a locking panel; while the other leads upwards to a platform opposite the entrance to the Grand Court Path. This large gap is traversable thanks to a series of Grapple Points. By swinging from them, Samus can also discover a short path leading to a White Blast Shield-covered door to Reliquary III.

- Gold Credit
- The Labor Golem in the center of the room must be reactivated by using the X-Ray Visor on a Combination Lock on the Golem. This moves it back into its former position, revealing a pool of Phazon. This also releases a couple of Phaazoids, one of which can be split into a Red Phaazoid. Killing it will reveal this Credit.

- Age of Science
- "The ships of Bryyo sped to the stars, in all directions, bearing the banner of peace. Soon we found stellar brethren in the Chozo, the Luminoth, and the Ylla. Starborn knowledge came to Bryyo, and we gladly sent our wisdom to our new friends in return. The hearts of Bryyo were filled with pride, and they honor the Lords of Science for all the wonders we provided. As the time of New Bryyo came to be, the old ways faded. The cries of joy from those who honored Science covered the angry shouts of those who mourned the old ways, the Primal Traditions."
