Just a short walk along the river from \u010cty\u0159koly, past the whispering pines and the bend where the Mnichovick\u00fd Brook meets the S\u00e1zava, the remains of Zlenice Castle (Z\u0159\u00edcenina hradu Zlenice) rise from a rocky promontory. Today, it\u2019s only a ruin \u2014 its great walls broken and softened by time \u2014 but this small fortress once stood as a proud sentinel over one of the most storied rivers in Bohemia.
What remains is known simply as Hl\u00e1ska, \u201cThe Watchtower,\u201d and it\u2019s easy to see why. The surviving stone tower still looms over the valley, watching as the S\u00e1zava curves and sparkles below. Yet few realize that this quiet place, surrounded by moss and birdsong, carries with it nearly seven hundred years of Czech history.
<\/p>\n\n\n\n

Zlenice Castle was founded sometime after 1300, built on a natural rock spur high above the confluence of the Mnichovick\u00fd potok and the S\u00e1zava River. The name Zlenice first appeared in written records in 1318, alongside Old\u0159ich of Zlenice, one of its earliest lords. The castle took its name from an older settlement that once stood on the opposite riverbank \u2014 a village that later disappeared but lives on through the fortress that succeeded it.
The architecture we see in ruins today dates from the first half of the 14th century, a time when Bohemia flourished under King John of Luxembourg (Jan Lucembursk\u00fd). Zlenice represented a typical nobleman\u2019s residence of the Middle Ages \u2014 fortified yet intimate, balancing defense with domestic comfort.
By 1351, the estate was held by Jan of Zlenice, who took his name from the castle itself. That same year, he lost ownership as part of a loan arrangement with the brothers \u0160t\u011bp\u00e1n and Je\u0161ek of Tet\u00edn \u2014 an early example of how politics, debt, and family fortunes intertwined in medieval Bohemia.
In the second half of the 14th century, Zlenice and the surrounding Pos\u00e1zav\u00ed region came into the hands of the powerful noble family of Dub\u00e1. One of its most distinguished members, Ond\u0159ej IV of Dub\u00e1 and Zlenice (1361\u20131412), was not only a lord but also one of the most influential legal scholars of his time.
Ond\u0159ej IV served as the highest judge of the Czech Kingdom under King Charles IV and authored the V\u00fdklad na pr\u00e1vo zemsk\u00e9 \u010desk\u00e9 \u2014 the first comprehensive Legal Code of the Czech Lands. To this day, historians regard him as one of the pillars of Czech medieval law and governance.
Under his rule, Zlenice became a feudal property, and the castle likely prospered as both a noble residence and a local administrative center.
When Ond\u0159ej IV died in 1412, Zlenice passed to the Czech Crown and then shifted through a series of noble families during the turbulent 15th century \u2014 a period marked by the Hussite Wars and shifting allegiances.
<\/p>\n\n\n\n

The estate was acquired by Bo\u010dek of Pod\u011bbrady and P\u016fta of \u010castolovice, who in 1415 sold it to Kune\u0161 of Konojedy. For a time, the Kune\u0161 family held the property, but after his death, his daughter B\u011bta lost it to Zden\u011bk Kostka of Postupice, sparking a prolonged dispute among creditors and heirs.
By 1456, the estate was sold to the Tr\u010dka of L\u00edpa brothers, only to be bought back again in 1463 by Zden\u011bk Kostka himself. It was during his tenure \u2014 between 1464 and 1466 \u2014 that the castle\u2019s final decline began. By 1465, Zlenice was officially described as \u201cdeserted and in ruins.\u201d
From then on, it passed into the ownership of the Komorn\u00ed Hr\u00e1dek estate, and later to the Konopi\u0161t\u011b estate, where it was folded into broader aristocratic holdings. Its defensive days were over; Zlenice had become a romantic relic of a fading medieval world.
The remains of Zlenice tell us much about medieval castle design. The outer ward, or courtyard, was separated from the main castle by a wide, rock-hewn moat, once crossed by a drawbridge that could be raised for defense. The core of the castle was irregularly pentagonal in shape, with the main entrance passing through a square gate tower.
<\/p>\n\n\n\n

Traces of seating niches, window frames, and a bridge mechanism can still be seen in the preserved masonry. The central tower, now the ruin\u2019s defining feature, once stood nearly 14 meters high with four floors, remnants of which survive on the northwest wall.
Visitors today can easily imagine the drawbridge lifting, guards pacing the rampart, and the S\u00e1zava glittering below \u2014 both a lifeline and a defense.
Like all good Czech ruins, Zlenice has its share of ghost stories. The most famous comes from Josef Sv\u00e1tek\u2019s 19th-century novel Zl\u00fd duch Zlenic (The Evil Spirit of Zlenice), which tells of betrayal, vengeance, and a restless spirit haunting the castle\u2019s shadowed corridors.
Though the tale is fiction, the romantic mystique it inspired remains. Locals say that when the fog settles low over the S\u00e1zava, the castle looks as if it\u2019s floating above the clouds \u2014 as if the centuries themselves never quite let go.
How to Visit Today
Zlenice lies near Senohraby, about 30 kilometers southeast of Prague, and can be reached easily from \u010cty\u0159koly by a pleasant 30\u201340 minute walk along the S\u00e1zava River hiking trail. The path winds through forested hillsides, over small wooden bridges, and finally opens to a clearing where the tower rises above the treetops.
<\/p>\n\n\n\n

The ruins are open year-round and free to visit. You\u2019ll find information panels, river views, and plenty of quiet corners perfect for sketching, reflection, or simply letting the past sink in.
Places like Zlenice Castle embody the kind of history I love sharing \u2014 not the grand or gilded, but the intimate and enduring. This small fortress lived, ruled, and fell long before our time, but its stones still hold the memory of everything Bohemia once was \u2014 noble, turbulent, deeply human.
As mentioned in an earlier post, for some time, my father and grandmother lived nearby, in a little cottage above the S\u00e1zava. I often think how easily they might have walked this same trail, crossed the same bridge, or stood in the shadow of Hl\u00e1ska at sunset. I never visited them there \u2014 my children were too young then \u2014 and I\u2019ve always been sorry I missed it.
Maybe that\u2019s why I return to these stories: to walk the paths I couldn\u2019t then, to keep the memory of these places alive.
