Markův mlýn

Markův mlýn is a former watermill on the middle course of the Loděnice stream, standing in the municipality of Unhošť close to the border with Chyňava, roughly 10 km west of Prague's edge. The site carries two layers of interest at once — a piece of historical milling heritage and a protected pocket of nature — making it an unusual but rewarding stop for anyone walking the Kačák stream valley.

Where does the mill's name come from?

The mill takes its name from the Marek family, respected burghers in Unhošť during the 17th century. Before that, the building was known under different names — "Pod Berounským brodem" (Below the Beroun Ford) and "Podhorský" (Below the Hill), both referring to its position relative to the terrain and nearby river crossings. From 1863 the mill passed into the hands of the Boček family, yet the older Marek name is the one that stuck in local usage and on maps.

How long did the mill operate?

The mill remained in operation until 1951, a comparatively long working life for a rural watermill in this region. Today the building survives in good condition, though it no longer serves its original economic purpose. A sizeable area of recreational cottages has grown up around it, and the mill itself has become a natural landmark and a crossing point for hiking trails that converge with unusual density in this stretch of the Kačák valley.

What does the "Markův mlýn natural monument" refer to?

The mill's name also lends itself to an official nature reserve designation (přírodní památka) covering two small localities near the building. The first is a meadow on a hillside about 200 meters north of the mill, next to a marked blue hiking trail. The second lies roughly 100 meters west of the mill, on an island formed where the river bends and the millrace branches off.

Why was the area protected?

The natural monument was established by a decree of the Kladno District Office, effective from December 21, 1993, covering land within the Unhošť cadastral area. Its purpose is to preserve unique plant communities typical of rocky steppe habitats — a rare environment in this part of Bohemia. The site holds a relatively abundant population of the protected Bohemian pasque flower (Pulsatilla pratensis subsp. bohemica) and a smaller population of Bohemian gagea (Gagea bohemica), both species sensitive to habitat change and dependent on the dry, sun-exposed microclimate of rocky slopes.

What else is worth seeing nearby?

Markův mlýn works well as a starting point for walks along the Loděnice and Kačák valleys, where several other historical watermills can be found. A marked route from Unhošť to the mill runs about 8 km through scenic, partly wooded riverside terrain. It's a spot where a walk through the traces of old milling industry can be combined with a look at rare steppe vegetation — a combination that's uncommon for the region.

Frequently asked questions

Can the mill be visited inside? Available information doesn't specify whether the interior is open to visitors — it's worth checking locally before a visit.

Is the site accessible by car? The mill sits among recreational cottages reached by local roads, but the most rewarding way to get there remains on foot, via the hiking trails of the Kačák valley.

Are there other natural attractions nearby? Yes — the Loděnice and Kačák valleys are dotted with further old mills and areas of natural interest, making the area a popular day-trip destination from Prague.
