Neoclassicism still determines our idea of museums, especially with regard to their architecture; but the policies implemented at the time concerning the display of antiquities in the vicinity of museums were also to be very influential in the long term. During the Enlightenment, the first museums of art and archaeology were often preceded by public displays of classical monuments assembled in porticoes and courtyards, sculpture gardens more or less accessible to visitors and other spaces of intermediation surrounding art institutions. As the nineteenth century advanced, that tradition was reinterpreted in such open-air environments, substituting ancient sculptures by new statues made in classical materials and attitudes. Recently, some postmodern practices have returned to the installation of ancient art works in front of museums.
