Columba n. 1. Roost for doves or homing pigeons. 2. Name of dove that brought the olive branch. 3. Constellation in the southern hemisphere.
This historical location and architectural gem was created before the turn of the last century (1898). The three story Greco-Roman structure features extensive Victorian ornamentation, and also presents a Victorian outlook on dignity and tribute. This place is meant to be visited and viewed.
This cache is a photographic letterbox hybrid—stamp or sign only. A guest register is slipped inside a 3 x 4 inch metal container, placed on a common area shelf. Other remembrances and mementos are also left on the shelf. Please be respectful of other people’s mementos and property. There is a bench to sit on, in the place called Argo.
Profound thanks, Princess Lea, for carving the letterbox stamp!

To find the register, follow the photographs that are the letterbox clues.
