The Porticus Periculum is a hall at Hogwarts Castle.

Behind the scenes

 * This hall can only be seen on the Marauder's Map replica on display at The Wizarding World of Harry Potter.
 * A "Porticus" is an entrance-porch of a church. "Periculum" is a Latin noun meaning "danger" and is also the name of a spell to conjure red sparks.
 * This may be a variant of the Siege Perilous of Arthurian legend, or the comic book "reinterpretation" of that concept.
