Libín, Stone observation tower on Libín mountain in the Šumava foothills near Prachatice, Czech Republic

Libín is an observation tower standing on a mountain ridge near Prachatice with a viewing platform that opens up to the surrounding landscape. The structure rises about 27 meters and sits at roughly 1100 meters elevation, providing sight lines across the Bohemian region and toward the distant Alpine range.

The Šumava Tourist Club, founded in 1880 and made up mainly of Germans from Prachatice and its surroundings, decided at its first annual meeting in January 1881 to build a tower on Libín. The design by Vienna architect Vyskočil was approved, funds came from member dues and donations, and after two years of construction the tower opened on 16 September 1883, named after Crown Prince Rudolf. In 1935 it passed to the Czechoslovak Tourist Club, and in 1994 it was repaired and repainted.

The tower owes its name to Crown Prince Rudolf, after whom it was christened at its opening on 16 September 1883; it was originally called Kronprinz-Rudolf-Turm. The building was funded by the Šumava tourist club through member subscriptions and donations from wealthy patrons.

The tower is accessible via two marked trails: a shorter blue route of about 2 kilometers from the Sedlýcko parking area or a longer red path of about 5 kilometers. Both routes pass through wooded terrain and offer options depending on fitness level and available time.

The tower's original name, Kronprinz-Rudolf-Turm, honoured Crown Prince Rudolf; it was renamed Libín after 1918. From the top, the source records views of Prachatice, the Novohradské hory, the Kleť mountain with its own tower and transmitter, the Brdy hills, and on very clear days the Alps.
