Třeboňské seníky, Wooden hayracks in Mokré louky, Třeboň II, Czech Republic

The Třeboňské seníky are log hay sheds standing freely in rows on the Mokré louky meadows northeast of Třeboň's historic centre. Each has a timber frame with a gabled roof; they are the last log buildings of this kind in the area, otherwise typical of mountain regions. They stored hay in summer, carted out in winter when the waterlogged ground froze.

The set of 54 hayracks was entered in the state register as a cultural monument in 1963 under number 3-2341, with protection retroactively dated to 3 May 1958. A 1971 repair campaign counted 54 structures, all with rot-damaged lower parts and broken roofs, and was carried out without conservation specialists. Summer floods in 2002 damaged many of them and moved at least one from its position.

The name seník refers to a log hay shed; the structures appear in paintings, literature and folk songs of the Třeboň region, and several were filmed, most famously in the 1952 film Pyšná princezna (The Proud Princess).

The haylofts stand on the Mokré louky meadows northeast of Třeboň's historic centre, reachable on foot or by bike; paths cross waterlogged ground. The city of Třeboň has restored ten of the structures, while many privately owned ones are in poor condition, so view them from the paths.

Many visitors expect to find similar timber structures in mountainous regions of Europe, yet these occupy a flat, wetland plain, making them architecturally atypical. This contrast reveals how local builders created practical solutions specifically suited to boggy terrain rather than following familiar patterns.
