Štefánik Observatory

About

The Štefánik Observatory, nestled in Prague’s Petřín Park, has been a beacon of astronomical exploration since 1928. Named after Milan Rastislav Štefánik—a Slovak astronomer, general, and co-founder of Czechoslovakia—the observatory was established to bring the wonders of the cosmos closer to the public. Its historic Zeiss double astrograph, acquired from Viennese astronomer Rudolf König, remains a centerpiece of its equipment. Today, the observatory offers daytime and nighttime sky viewings, interactive exhibitions, and guided tours that blend science with history. With its scenic location and commitment to public education, Štefánik Observatory continues to inspire curiosity across generations.

Location

The Štefánik Observatory is located on Petřín Hill in the center of Prague, specifically at Strahovská 205, in the Malá Strana district. Founded in 1928 and named after Slovak astronomer Milan Rastislav Štefánik, the observatory is situated near the historic Hunger Wall, which dates back to the reign of Charles IV in the 14th century. It offers a permanent modern astronomical exhibition and features multiple domes with large telescopes for observing the Sun by day, and the Moon, planets, stars, and galaxies by night. Nearby the observatory, visitors can enjoy the scenic Petřín Park, which provides a lush green space with panoramic views over Prague. The Petřín Lookout Tower, reminiscent of a small Eiffel Tower, is close by and can be combined with a visit to the observatory for a fuller cultural and natural experience. The area also invites exploration of the charming Malá Strana district with its historic architecture, cafes, gardens, and walking paths. The observatory is accessible via a pleasant walk or scenic cable car ride through the park, making it a rewarding stop for those interested in astronomy, history, and outdoor leisure in Prague.
