Puebla's Xanenetla neighbourhood is noted for its collection of murals (Murales De Xanenetla). 2 of 2. In 1987, UNESCO declared 600 blocks of Puebla’s historic city center — including Xanenetla — a World Heritage Centre. The Xanenetla barrio today is visually unique, mixing 16th- and 17th-century architecture with the contemporary urban art of Puebla Ciudad Mural. Xanenetla received its name as the land (between the banks of the San Francisco River and the hills of Loreto and Guadalupe), was full of a light sand called Xalnenetl. This material was combined with “the good mud of the area” for the production of bricks. The settlement was called “Las Praderas de Xalnene” in 1751 and it was not until later that its name changed to Xanenetla.
