We have been noting the heritage of signs at various sites in State Guardianship in England, Wales, and Scotland. The complexity of architectural features at archaeological sites in Greece is resolved by the placing of signs to explain the elements to visitors.
In this view of part of the temenos of Apollo on Aegina (the Kolonna site), the different phases of the sanctuary wall (one from the archaic period, and the other from the Late Roman phase) are indicated in Greek and German (reflecting the language of the excavators of the site).
Yarmouth Castle on the Isle of Wight retains some of its original Ministry signs including this information board close to the entrance. The blank section at the bottom would have indicated (using similar signs), ‘This monument is in the care of the Ministry of Public Buildings and Works [or Ministry of Works] / It is an offence to injure or deface it’.
