Curious students and faculty trickled into Sibley Hall yesterday afternoon to hear Barbara Penner, lecturer in architectural history in the Bartlett School of Architecture at University College London, elucidate the relationship between bathrooms, social boundaries and architecture.

As Penner took the podium, the house lights fell to yield the title, “X is for An Expert on Bathrooms: Alexander Kira & Peter Greenaway’s 26 Bathrooms,” brightly projected onto the screen behind her.

The lecture featured a screening of Peter Greenaway’s 1985 film entitled Inside Rooms: 26 Bathrooms.
