The Gardens of Night are situated in Drefia, here and play a role in The Gravedigger of Drefia Quest. They were introduced in Updates/10.1, with the revamp of Drefia and the introduction of said quest. The gardens contain some items which are needed in various quests. According to Omrabas the gardens are located:

Behind a Counter you can find several (unreachable) items such as a Rough Red Gem, a Leechbloom a Reagent Flask, a Bottle with Rat Urine, a Fleshy Bone together with an Infernal Frog.

There are also two Monuments, one reading "Eternal Life" and one reading "To the Dark God".

There are also Pillars with Hallowed Bonepiles next to them.
