Esplanade – Theatres on the Bay is a performing arts centre located in the Downtown Core of Singapore near the mouth of the Singapore River. Named after the nearby Esplanade Park, it consists of two rounded structures: one housing a concert hall with about 1,600 seats; and the other a theatre with a capacity of about 2,000 for the performing arts.

Performing arts center/centre, often abbreviated as PAC, is used to refer to:A multi-use performance space that is intended for use by various types of performing arts, including dance, music and theatre.The intended multiple use of performing arts centers in this sense differentiates them from single-purpose concert halls, opera houses or theatres, although the actual use of single-purpose spaces for other than their intended use is widespread. This sort of space has a long history, extending to the Roman Colosseum and Greek amphitheatres.A cluster of performance spaces, either separate buildings or under one roof, each space designed for a specific purpose such as symphonic music or chamber music or theatre, but multipurpose as a whole. The modern version of this came into being only in the 1960s.Examples of this type of PAC are the Kennedy Center in Washington, D.C., the Sydney Opera House, and the Lincoln Center in New York City.
