The Monastery gate is a location in Diablo II. It is located just after the Tamoe Highlands. It grants access to the Rogue Monastery and its Outer Cloister. The Rogue Monastery guards the way East. The citadel is now being guarded by Andariel, who prevents anyone from chasing Diablo. There's another, larger gateway leading through the Monastery; this is most likely the aforementioned way East, leading through the mountains and into the lands of Aranoch. However the wooden portcullis is lowered.
