A precinct is a closed or clearly marked space which belongs to an organisation. Around some main buildings, such as a cathedral or college, is a space. This space may have other buildings in it, and usually has a wall round it. The whole area has one owner (such as the church). Persons may only come into the precint if they are allowed: it is not a public space, even though members of the public may use it. For example, students and staff may enter a college, but visitors will have to give reasons at the entry.
