Rozhledna Špulka, Observation tower in Lbosin near Divisov, Czech Republic

Rozhledna Špulka is a wooden and steel observation tower on Březák hill at 530 m above sea level near Lbosín. Its base measures 10.7 m in diameter, the middle section 3.4 m and the upper viewing platform 5.8 m; a 150-step spiral staircase with 20 cm risers leads to the viewing level at 30 m.

Construction of the wooden and steel tower began on 27 April 2013 and it opened to the public on 26 April 2014. The design by architect Iveta Torkoniaková of 2T engineering won the Club of Friends of Observation Towers' "Observation Tower of the Year 2014" award.

The name Špulka means spool, and the tower's spiral of 150 steps winding around a narrow core gives it that shape. The design is by architect Iveta Torkoniaková with the firm 2T engineering. A kiosk by the tower sells refreshments, tourist stamps and souvenirs.

Access is via the 1.2 km Ptačí stezka nature trail from the Lbosín car park, or since 2015 via a gravel path from a field car park near road 111 (exit 41 of the D1 motorway), about 950 m. Another car park for roughly 30 cars lies 2 km away on the Teplýšovice–Humenec road.

The 150-step spiral staircase rises 20 cm per step, and in clear weather the summit view reaches both the Šumava range and Sněžka. The tower won first place in the "Observation Tower of the Year 2014" poll held by the Club of Friends of Observation Towers.
