Monte Mario Observatory

Monte Mario Observatory is a research facility positioned on Rome's highest elevation with comprehensive astronomical equipment. The site includes specialized instruments and work areas designed to support various types of astronomical observation and research.

The facility was founded in the early 1920s and became significant for Italian cartographic work during the twentieth century. Its establishment contributed to the development of modern surveying methods and scientific reference standards.

The Astronomical Copernican Museum within the facility houses a rich collection of scientific works and manuscripts spanning centuries of astronomy. This collection reflects how different eras understood the cosmos and our place within it.

The location sits on a hillside, so visitors should expect some elevation change and wear comfortable shoes for walking. It helps to check opening hours before visiting, as access may be limited to specific times.

The facility includes dedicated learning spaces that demonstrate how modern astronomical research works in practice. These specialized areas give visitors hands-on experience with astronomical concepts and methods.
