What is the name of the well-preserved ancient Roman house in Pompeii with famous erotic frescoes?

The well-preserved ancient Roman house in Pompeii with famous erotic frescoes is the House of the Vettii.

The house was owned by Aulus Vettius Conviva and Aulus Vettius Restitutus, two successful freedmen whose wealth allowed them to create an impressive urban residence. It was preserved when Mount Vesuvius erupted in AD 79, burying Pompeii under volcanic material.

Its surviving decoration is especially notable for Fourth Style Pompeian frescoes, including mythological scenes and explicitly erotic imagery. The house also contains a large peristyle garden decorated with sculptures and wall paintings, giving historians a vivid view of Roman domestic life.

A common mix-up is the Villa of the Mysteries, another Pompeian building famous for its painted rooms. The House of the Faun is larger and better known for its Alexander Mosaic, while the House of the Tragic Poet is associated with a famous mosaic of a chained dog.
