In recent years the Thai authorities have made substantial efforts to restore and make accessible to visitors several major Cambodian and Thai archaeological sites. The principal expression of such efforts is the demarcation of nine historical parks, among which the recently restored Cambodian temple of Phanom Rung has achieved great publicity, not only for touristic, but also for nationalist reasons. An increasing number of palaces and historical buildings and museums have also been opened to the public; some became important sites for foreign, and even more, domestic tourism.
