The Lupanar is the ruined building of an ancient Roman brothel in the city of Pompeii. It is of particular interest for the erotic paintings on its walls, and is also known as the Lupanare Grande or the "Purpose-Built Brothel" in the Roman colony. Pompeii was closely associated with Venus, the ancient Roman goddess of love, sex, and fertility, and therefore a mythological figure closely tied to prostitution.
