Excavations at Akrotiri on Thera, where some house roofs remain intact, have shown that U-shaped terracotta drains, set projecting out beyond the outside walls, drained roof terraces. These terraces were often surrounded by built parapets.
What then of contemporary Neopalatial buildings on Crete, where construction and style are similar but much less is preserved? Evidence for the appearance and use of roofs and parapets there consists of drains that seem to have fallen, as now reported at various recently excavated sites (Kommos, Mochlos, Palaikastro); also staircases that probably led to the roof; and architectural depictions (a model, plaques).
