The Love Chamber, also known as the Ever-Locked Room, is the only room within the department that remains behind a heavily locked door. This door cannot be opened by Alohomora or any magical unlocking pen knives. Behind this door is the most mysterious subject of study in the department: the emotion love. In the middle of this large room is a fountain of Amorentia, which may make Unspeakables that wander too close a little distracted. To the left of this fountain are many cauldrons, which are used to try to understand love potions. To the right is where the research and study of charms and spells related to love takes place. There are powerful forces at work within this room, and any Unspeakables that work in here are trained to be able to withstand these forces.

Work within the Love Chamber is split into three divisions: the love specialists who are general specialists concerned with studying love, potioneers who study the aspects of love related to potions, and charmists who study the aspects of love related to spells.
