Lower City Sewers is a location that the party can enter during Act Three from several access points found throughout the Lower City area of Baldur's Gate. Entrances to the Lower City Sewers include manhole covers that are visible from the city streets, but additional passages can be found inside specific buildings.

Abandoned Cistern

While inside the Lower City Sewers, the minimap name will become "Abandoned Cistern" from multiple directions including:

• North of a "ramp" towards a broken stone wall, at roughly X: -167 Y: 864.
• West through a door, with caustic brine on the ground on the other side, near X: -155 Y: 877

The large black pipe, running in an L-shape through the middle of this room, is another visual landmark to help to identify if the party are in the right area.

While the minimap name reads "Abandoned Cistern",

• A locked Sluice Gate must be opened to access the second half of the area. It cannot be lockpicked. To open the gate, either make a DC 25 Athletics check to turn the Sluice Valve, or turn the Water Level Valve and Temperature Valve until they are both at the perfect level. Use the Emergency Release Valve if either level gets too high.
• Ladder X: -283 Y: 878 can be found past the Sluice Gate in a stone alcove at the back of the room. On interaction, causes a screen transition which leads to an area called "Gardener's Basement." This has another exit that leads to a door labeled "Keep Out" in the Lower City.

Minsc can be found here as part of the quest The High Harper, along with various hostile dopplegangers and Bhaalists. If saved, Minsc will subsequently break through a wall to a hidden area to the north, seeking Boo, his animal companion. The first room in this area has a set of nonlootable artifacts, presumably mementos of the heroes that accompanied Gorion's Ward during the events of Baldur's Gate I and II. These include a halfling-sized warhammer, representing Mazzy Fentan; a turnip for Jan Jansen; a mailed fist for Keldorn Firecam; a pair of carved wooden wings for Aerie and a cracked wooden mask, representing Dynaheir. Beyond is another chamber where Boo can be found.

Guildhall

Main Article: Guildhall

Base of operations for Baldur's Gates' infamous criminal faction, The Guild, headed by Nine-Fingers Keene.

From the Guildhall, an additional exit to the sewers can be opened if the party discovers Nine-Fingers' Secret Sewer Vault.

Undercity Ruins

Main Article: Undercity Ruins

While inside the Lower City Sewers, the minimap name will become "Undercity Ruins" by walking north through a stone archway at roughly X: -138 Y: 907. The waypoint of the same name is usually visible from this path. Inside the ruins is a door X: -133 Y: 934 initially closed and locked, requiring special means to open, and a passageway X: -181 Y: 935 heading west, leading to the Ancient Lair upon interaction.
