Ördögház (Hungarian for Devil(s) House) is a fictional building from the Underworld series, located in Hungary near the town of Szentendre. It is located on the Danube bank at the foot of the Pilis Hills, due north of the city of Budapest. Ördögház has served as the seat of power for the Vampires since the loss of Castle Corvinus, before it was burned to the ground by Marcus Corvinus early in the events of Underworld: Evolution.

Underworld

In Underworld, the ancient building houses a gathering of the Old World Coven, ruled by the Vampire Elder Viktor. Every century, a Vampire Elder returns to their sarcophagus in the Elder's Chamber/Crypt, located in the lowest level of Ördögház, to hibernate for the next two centuries, while another Elder is awakened to lead the Coven.

It is unknown if Ördögház is a permanent home to the current occupants seen in the first film and is open to the entire Coven, or if it is only open to a select few at certain times of ceremony, such as Awakenings.

The grounds are fenced and patrolled by armed sentries with dogs and modern electronic surveillance devices are in place.

At the time of the events of Underworld, Kraven is the acting regent of the mansion.

Underworld: Evolution

In Underworld: Evolution, Marcus Corvinus burns Ördögház to the ground after killing all of the mansion's inhabitants. When Samuel comments to Marcus's father that Marcus destroyed his own Coven, Alexander notes that the Coven never belonged to Marcus in the first place, a reference to Marcus's rivalry with his fellow Vampires Elders, Viktor and Amelia.

Rooms

Within Ördögház are several rooms, most of them the personal chambers of various Vampires.

Elders' Chamber

In the lower parts of the mansion lies the Elders' Chamber, a room designed to hold the coffins of the hibernating Vampire Elders. A large portion of the chamber is dedicated to an open floor, underneath which lie the hibernating Elders. Ornate designs centered around the symbols of each Elder (A, V, M) contain a turning mechanism that, when applied, opens the hatch, causing the Elder's coffin to rise into the air so that a blood drip can be administered, awakening the sleeping Vampire. Once the coffin is fully removed, the hatch automatically returns to its original position.

Further back in the room is a recovery chamber containing various instruments and blood bags, used to revive the Elders to full strength. A contraption consisting of several tubes hangs from the ceiling, designed to be attached to the body of the waking Elder to administer large quantities of blood directly into their system. A single throne sits at the front of the recovery chamber, in which the Elders will lounge as they recover.

The Elders' Chamber/Crypt is carefully guarded by Death Dealers at all times to insure the Elders are not awakened ahead of schedule. During the events of Underworld, a Death Dealer named Duncan is in charge of guarding the Crypt.

Library

A large library can be found inside the mansion, packed with books of various subjects. Because the hedonistic Vampires of the mansion are uninterested in the past, the room is largely untouched, and even the maids refuse to venture there. A thick layer of dust covers everything, and books seem to be piled haphazardly throughout the room. Within the library is a locked room, which contains books and records related to the history of the Vampire species. The Vampires are forbidden to enter this part of the library, as digging into the past is forbidden by the Elders.

Dojo

The Dojo is the base of operations for the Death Dealers, the warrior elite and military of the Vampire Nation. It is located in the renovated attic loft space of Ördögház.

Known aspects of the Death Dealers' Dojo include sparring mats; where Death Dealers practice hand-to-hand combat and martial arts, and an armory that boasts an impressive collection of weapons, ranging from medieval and exotic knives, daggers and swords, to a wide range of firearms with silver-plated ammunition. There is also a firing range; soundproofed, complete with ceramic busts used for target practice.

Kahn's workspace is also here, where he creates the silver nitrate bullets after reverse-engineering the Lycans' Ultraviolet ammunition.
