zdymadlo Hořín Water structure
The Hořín is part of the lateral navigation channel Mělník - Vranians and occupies a key position in the Vltava navigation system. With its drop of 8.5 metres, the highest level of navigation in the section Prague - Mělník is above the height of the air of the Vranian Jez. In the process Vltava follows the wall of Miříjovice and is among the most interesting objects of Czech sailing engineering.
The project was developed by František Sander and the work was put into operation in 1905. The design solution was innovative for its time: the lock consists of two lock chambers placed side by side. The dimensions of the chambers shall be 137 × 20 metres and 73 × 11 metres, with a difference in size corresponding to the needs of diverse ship traffic. The operation of both chambers is provided by bypass channels along their entire length, which are filled and emptied by water. This technical solution has proved itself and its principles remain in operation today.
The original equipment gradually replaced modern technology. Control mechanisms have given way to hydraulic control and computer control, which allow safe and efficient operation. Part of the authentic technical equipment from the beginning of the twentieth century can be viewed directly on site next to the lock chambers. In 1996, a small hydropower plant with a Francis turbine of 30 kW was put into operation. The original turbine from the beginning of the last century is now exhibited in the exhibition of water engines of the Technical Museum in Brno.
In recent years, the lock has been upgraded. In June 2019, building modifications were initiated during which a lifting mechanism was added to the stone lock portal. It allows ships to travel up to seven metres high, thus extending the range of vessels that can pass through the channel. The construction work, during which the bridge was closed and the ferry was introduced, lasted until September 2021. The functional test was carried out on 18 September 2021.
The Hořín is a unique witness to the development of Czech sailing engineering. The visitor will see a functional technical landmark and history of adapting traditional solutions to the requirements of modern times.

The Hořín lock is part of a shipping canal that runs parallel to the Vltava River between Vraňany and Mělník. Downstream, it is followed by the Miřejovice lock and overcomes the height of the Vraňanský weir. The drop that boats overcome at Hořín is eight and a half meters. It is the highest navigation level on the section between Prague and Mělník. The structure was designed by František Sander and today it is protected as a technical monument.
The lock was put into operation in 1905. It consists of two navigation chambers placed side by side. The larger one measures 137 by 20 meters, the smaller one 73 by 11 meters. Water flows into the chambers and flows out of them through bypass channels that run along their entire length. Part of the original technical equipment is displayed next to the chambers. The current control mechanisms are hydraulic and are operated by a computer.
In 1996, a small hydroelectric power plant with a Francis turbine with an output of 30 kilowatts began operating at the lock. The original Francis turbine from the early twentieth century has been preserved and can be seen in the exhibition of water motors at the Technical Museum in Brno.
In June 2019, the reconstruction of the navigation chamber began. A lifting mechanism was added to the stone portal, which allows taller boats to pass through the lock, up to a height of 7 meters. The bridge that crosses the lock was completely closed during construction. People were therefore transported by ferry from the nearby mouth of the canal into the Labe to the right bank of the Labe. The work was completed in September 2021 and on September 18, 2021, a functional test took place.
Tips for visitors
Best time to visit the Hořín lock is in spring or autumn when nature is around the most beautiful and temperatures are pleasant. In summer there can be a lot of excitement, especially near Vltava, where families often meet children. In spring you can see how the water in the canal and river changes with the melting of snow and in autumn you can enjoy the golden colours of leaves in the surrounding forests. In winter the visit is possible, but some parts of the area may be difficult to access due to snow.
If you arrive by public transport, the nearest stops are nearby, but the current connection is good to check in the traffic search engine. The stops are usually in the village Hořín or in neighbouring villages.
Take comfortable shoes when visiting, because the area of the lock is partially uneven and there are roads along the Vltava and in the forest. It is also appropriate to wear a raincoat or umbrella because the weather can change quickly. If you plan to stay by the water, don't forget your sunglasses and sunscreen. It is good for children to have some games or small activities with them because there is not always enough room for running.
The best places for shooting are, of course, the lock itself and its mechanical parts, which are technically interesting. The views of Vltava and surrounding forests are also interesting, especially at sunset, when light gives the landscape a golden shade. For quality images it is advisable to come in the morning when light is softer. It is also possible to get interesting photos with children who can play on the river bank.
In the vicinity of the wall Hořín is worth visiting Karlstejn Castle, which is located about 15 kilometers away. This medieval castle is one of the most visited in the Czech Republic and offers rich history and picturesque views. Another interesting thing is the city of Mělník with its historical centre and castle, which are about ten kilometres away. Both of these places are easily accessible by car or public transport and are ideal for a day trip.
For families with children there are several activities that can make a visit a fun experience. Children can see the working mechanisms of the lock and explain how the water transfer works. It is possible to play on the shore of Vltava in the surroundings, but it is important to explain the safety rules to children. In the nearby Mělník or in the castle Karlstejn are also interesting for children because they offer interactive exhibitions and possibilities to explore historical sites.

Seasonal recommendations
Spring Hořín offers a unique atmosphere in spring months, when the awakening nature projects into the sun's glare on the water surface and moist green surrounding meadows. After the winter rains, the river's level often rises, creating dramatic water surfaces and the sounds of snorting water that accentuate even more. At this time it is ideal to visit the memory early in the morning, when the larger crowds of tourists do not yet appear and the sun falls directly on the technical details of the water work. Comfortable shoes and light but wind-resistant clothing are recommended because spring weather can be variable - from sunny days to sudden showers. The best time for the tour is between April and May, when nature is blooming and the technical elements of the lock are well visible at a more stable water level.
Summer In the summer months, zdymadlo Hořín becomes a popular target for families and cyclists who come here to take advantage of nearby cycling paths and pleasant shade under trees. Warm sunny days create mirror reflections on the water surface, which together with insects living by the water create a calm but lively atmosphere. The best thing to do is to come here early in the morning or late in the afternoon to avoid the biggest crowds gathering in the high summer season. It is recommended to light but protective clothing against the sun, hat and plenty of water because in July and August it can be very hot. For those who want to explore the wider surroundings, it is advisable to pack small sailing or picnic equipment, because there are plenty of resting places in the surrounding area.
Autumn Autumn visit of the Hořín lock brings unique colour, when the leaves of the surrounding trees turn into golden and red shades that are reflected in calm water. Colder air and lower river levels after the summer rains reveal the technical details of the water works that are better visible at this time. The air is cleaner and quieter, making the visit an ideal choice for those looking for a peaceful environment. It is recommended to wear warmer clothes because evenings can be cold, and comfortable shoes for walking around the surrounding roads. The best time to visit is in September and October when nature is the most beautiful and crowds of tourists are smaller than in summer. In advent time there are also often small regional events associated with water works, which are worthy of attention.
Winter Winter zdymadlo Hořín offers a mysterious and peaceful atmosphere, where frozen or almost frozen water creates ice crusts and reflections that give the place a magical look. The snow covering the surrounding landscape and the technical elements of the water works creates a contrast between old stone structures and white nature. At this time it is advisable to visit the memory in the morning when the light is brighter and the opening time is longer than in the late afternoon. It is recommended to warm but comfortable clothes that protect against wind and cold, and waterproof shoes because the surrounding area may be frozen or contaminated. The best period for visiting is from December to February when nature is the most beautiful and technical details of the lock are well visible at low water level.
