A brothel, also known as a borello or whorehouse, is an establishment specifically dedicated to prostitution, providing the prostitutes a place to meet and to have sex with the clients. In some places, brothels are legal, and in many countries, places such as massage parlor are allowed to function as brothels, with varying degrees of regulation and repression. Depending on zoning, brothels may be confined to special red-light districts or 'tolerance zones'.
