Pod Ostrou Horou

Pod Ostrou Horou is a small nature monument located south of the village of Záhoří and southeast of Chroboly, in the Prachatice District of South Bohemia, Czech Republic. The protected area preserves damp meadows that are home to the Siberian iris (Iris sibirica), a species that has become increasingly rare across Central Europe's farmed landscapes due to drainage and the intensification of meadow management.

Why was the area protected?

The reserve exists to safeguard wet meadows as habitat for the Siberian iris. The plant typically blooms in May and June, producing distinctive violet-blue flowers that stand out against the surrounding grasses and sedges. Meadows like this depend on regular but low-intensity mowing — without it, they become overgrown scrub and lose their ecological value, which is why the site was placed under formal legal protection.

The nature monument was designated on 15 April 1992, during a period when Czechoslovakia (and later the Czech Republic) was formally protecting many small but ecologically valuable pockets of farmland — meadows, wetlands and field margins that had survived outside the boundaries of the country's larger national parks.

What can visitors see?

The main attraction is the meadow vegetation itself. Alongside the Siberian iris, the area supports grasses, sedges and other plants typical of damp lowland meadows. This is primarily a botanical and landscape site rather than a scenic viewpoint — there are no lookout towers or dedicated educational trails here. The reserve sits in the quiet, rural countryside of the Prachatice region, surrounded by fields and the forested foothills of the Šumava mountains.

How to get there?

Pod Ostrou Horou lies in an easily reached part of the Prachatice District, close to the villages of Záhoří and Chroboly and not far from the town of Prachatice itself. Its approximate coordinates are 48.9419 N, 14.0991 E. The surrounding area is served by local roads, though — as with many small Czech nature reserves — there is little dedicated tourist infrastructure, so a map or GPS navigation is worth having on hand.

When is the best time to visit?

The most rewarding time to visit is late May into June, when the Siberian iris is in bloom and the meadow is at its most visually striking. Outside this window, the site has a more subdued, typically rural character — still of interest to nature enthusiasts, but visually less dramatic.
