 | | The European Southern Observatory's (ESO's; external link) first observatory, with which Europe established its access to the southern hemisphere, was built on La Silla, a 2400-m high mountain in the Chilean Andes, north-east of La Serena (some 500 km north of Santiago de Chile). |

 | | ESO now has a new, second-generation observatory on Mount Paranal, the Very Large Telescope (VLT), about 500 km to the North of La Silla. |
