Parque Ecológico Loreto y Peña Pobre is a protected urban woodland built on the site of a former 19th-century paper mill. It features a unique blend of industrial heritage and natural conservation, incorporating the ruins of the factory into the landscape design. The park serves as an ecological buffer zone in the Tlalpan borough, preserving native flora and volcanic soil characteristics. It contains walking trails, outdoor exercise areas, and significant green space that aids in local microclimate regulation. The area is distinct for its combination of historical masonry and dense arboreal coverage. It acts as an educational space focused on environmental preservation and local history.
