A house of assignation is a term used to describe a place where sexual activity takes place in exchange for money. It is also referred to as a brothel, bawdy house, whorehouse, or a bordello. These establishments have existed throughout history and have been the subject of sensationalism, controversy, and criminal prosecution. Some other words used to describe a house of assignation include a house of ill repute, a red-light district, and a pleasure palace. The use of euphemisms for these types of establishments is a common practice, as they are often illegal and carry social stigmas. Despite being illegal in many places, houses of assignation continue to operate in secret locations and under the radar of law enforcement.
