In Path of Exile 2, in the region Cemetery of the Eternals you will need to open the Memorial Gate as part of the quests Sorrow Among Stones & The Mysterious Shade.
To do this, you will first need to find two keys: Asinia’s Memorial Key Piece + Draven’s Memorial Key Piece. These are dropped by the bosses inside two different dungeons: Mausoleum of the Praetor + Tomb of the Consort. Both dungeons are accessed from the Cemetery of the Eternals.
Clear both dungeons, the boss in each one will drop a key. After finishing both dungeons go back to Cemetery of the Eternals and run around the edges of the area to find the Memorial Gate. Because the map layout is different for every player in every instance the exact location will vary, but it should always be along the edge of the area. Now interact with the gate to open it.
