 Porches sometimes occur as part of the original design of a facade.This is very much the case in Italy, where they are usually only one bay deep and are supported on two columns, often resting on couchant lions, as at St Zeno, Verona.See above.Elsewhere, porches of various dates have been added to the facade or side entrance of existent churches and may be quite a substantial structure, with several bays of vaulting supported on an open or partially open arcade, and forming a sort of narthex as at the Church of St Maria, Laach.See above In Spain, Romanesque churches often have large lateral porches, like loggias.
