Many famous ancient sites have undergone some reconstruction using modern materials. Teotihuacan has seen restoration work where concrete and modern materials have been used since the 1960s. Angkor Wat's stones have been cut and reconstructed using modern tools for conservation. Chichen Itza has modern infrastructure including restaurants, parking lots, and souvenir shops to serve visitors. The Great Sphinx has had restoration work, including repairs and additions over the centuries. However, claims about widespread use of steel and rebar at sites like Stonehenge and Baalbek are largely inaccurate—Stonehenge has only had minimal stabilization of fallen stones, and such heavy materials are not typically used in authentic archaeological restoration.
