Monte Oliveto Maggiore: While facing the church’s east wall, clamber up to the low roof on the left-hand (southern) side. Then make your way over to the base of the bell tower, which sports a Glyph on its eastern wall.
Antico Teatro Romano: From the Teatro’s main entrance, hang a left and head toward the opening of the tunnel that runs around the ruin’s perimeter. The Glyph should be immediately visible once you get close.
Santa Maria Assunta: While this Glyph is advertised as part of the Torre Grossa, that’s actually misleading; in fact, you don’t need to climb the tower at all. Instead, stand in the plaza directly to the north of Santa Maria Assunta, face its main entrance to the west, and walk into the archway immediately to the left of it. The Glyph is at the end of the hall.
Torri dei Salvucci: There’s a little rooftop in between these twin towers; just climb up to it and look at the walls around you.
Torre dei Diavolo: All you need to do is climb to the top of this massive tower; the Glyph is on the little building at its peak.
