Database: Torre dell'Orologio

REBECCAC84: One of those strange glyphs Shaun mentioned is on this landmark. You should go find it!

Constructed in the late 15th century as a display of Venice's wealth, the Torre dell'Orologio displays the time of the day, the current phase of the moon, and for those of us who believe that all of human behaviour is governed by little shapes in the stars, the dominant sign of the Zodiac.

According to legend, the designers of the clock face were blinded once their work was complete, so they could never duplicate it elsewhere. While this is probably bollocks, the designers did live inside the clock tower for the rest of their lives to maintain it.
