Starý Stránov Castle

Starý Stránov is a scenic medieval ruin of a small stone stronghold, perched on a rocky outcrop above the left bank of the Jizera River, right over the hamlet of Zámostí near Písková Lhota. Only fragments of its walls survive today, yet the site still carries a raw, romantic atmosphere and draws hikers exploring the middle stretch of the Jizera valley.

How to get there?

Zámostí lies in the Mladá Boleslav district of central Bohemia, close to Písková Lhota and Horky nad Jizerou. The ruins are reached via a red-marked hiking trail that runs from Horky nad Jizerou, continues through Krnsko, and heads on toward Mladá Boleslav. The rocky spur on which the stronghold stands rises directly above the riverbed, making the spot a natural viewpoint over the Jizera valley in its own right.

What will you see?

The stronghold was built without a tower, as a single-section complex centered on a multi-story, unvaulted palace building. Its only gentle approach, from the south, was defended by a ditch and an outer gate, while the north and east sides relied on the natural protection of a steep ravine dropping toward the river, reinforced by a substantial additional ditch. Today the long outer wall of the palace, facing the Jizera, survives almost intact, along with both shorter side walls, which still show traces of former window and floor-beam openings. Fragments of the surrounding fortification walls can also be made out. Over the centuries, stone from the ruins was reused to build houses in the area, and several modern buildings now stand within the former ditches and directly on the grounds of the old stronghold.

The earliest written record of the site dates from 1297, when it was held by Mikuláš of Hrádek. Soon afterward it passed to the Myška family, who rebuilt the original wooden fortlet into a stone stronghold — the origin of one of its older names, Myškův hrádek. The Myšas held the site until 1492, when it passed to the Stránovský family of Sovojovice. From that point the stronghold began to be called Starý Stránov, or "Old Stránov," to distinguish it from a newer seat the family built elsewhere. The Stránovskýs did not permanently reside at the old stronghold, and the building gradually fell into disrepair, leaving only the walls visible today.

Because of its position, the ruin has also been known as Hrádek nad Jizerou or Hrádek nad Zámostím — names that point both to its closeness to the river and to the hamlet lying at the foot of the hill.

When to visit?

As an open-air ruin, the site is best visited in spring and summer, when longer days and milder weather make the walk along the red trail and around the outcrop itself more comfortable. In autumn the area tends to be quieter, which suits visitors who prefer exploring history away from crowds. Since this is a protected archaeological site, care is needed when moving around the grounds, particularly near the edge of the ravine and the former ditches.

Frequently asked questions

Where does the name Starý Stránov come from? The name appeared after 1492, when the stronghold passed to the Stránovský family of Sovojovice, who also held a newer seat elsewhere — hence the distinction between the "old" and "new" Stránov.

Who originally controlled the site? The first record, from 1297, names Mikuláš of Hrádek as its holder; the site was later held for decades by the Myška family, who converted the original wooden fortlet into a stone stronghold.

What has survived from the original structure? The long outer wall of the palace facing the Jizera still stands, along with both shorter side walls showing traces of windows, plus fragments of the fortification walls and remnants of the ditches.

How do you reach the ruins? A red-marked hiking trail leads there from Horky nad Jizerou through Krnsko toward Mladá Boleslav, with the stronghold itself standing on a rocky spur above Zámostí.
