An official at Spain's Alhambra palace says a Jordanian tourist was caught carving his initials with a coin into a wall of the complex that is considered a gem of Moorish architecture.
The official says the incident took place Aug. 13 and the man was detained, spent a night in jail and went before a judge before being released pending trial.
He is charged with damaging a building classified as part of Spain's historic heritage.
The official said the spot where the man etched can be restored.
The official at the Alhambra's board of trustees spoke on condition of anonymity in line with board policy.
The Alhambra, in the southern city of Granada, is a UNESCO world heritage site and Spain's most-visited tourist attraction.
