Conservation image Maya Initiative (1999–2009)
A project of the Getty Conservation Institute

The Hieroglyphic Stairway is currently in overall stable condition; equilibrium exists between the stone and the environment. This stability is the result of the installation of a protective shelter that, since 1985, has maintained consistent dry and warm conditions throughout the year by blocking rainwater and direct sunlight and eliminating condensation formation on the stones, thereby preventing cycles of wetting and drying, and excessive cooling and heating condition changes. Every two years the fabric of the shelter has to be replaced. This operation requires a full day of work for a team of ten persons and favorable climate conditions. Photo: Eliud Guerra.
