Senec is mentioned in written sources for the first time in 1252 as a villa (village) Zemch.

As in many other locations of the upper Rye Island and villages in the vicinity of today’s Bratislava, it was largely influenced by the majority of German ethnic group in the Middle Ages. The local Church of St. Nicholas is mentioned in written records since 1323. The location, situated on the border of the Danube Hills and the Danube Lowlands, has gradually become the central point of its surroundings. In addition to the church, the local weekly markets dating back to 1333 and the trade routes that led in this direction played a major role. Due to them, Senec is referred to as a toll station since 1412.


The biggest landmark that has made the town famous both locally and abroad are the Sunny Lakes.

The origin of the Sunny Lakes is related to the intensive dredging of gravel since 1845, which was mined here by the Hungarian railway construction administration for the construction of the Bratislava – Galanta railway. Intensive dredging created five separate water units, which were merged into one unit by mining. This is how the lake was created, covering an area of over 100 hectares, with a depth of up to 12 metres in some places.

The possibility to use the lake, called ‘dredger ‘ as a natural swimming pool was used in 1919 by the organization called ‘Slovenská Beseda’ in Senec. They marked out and fenced off the water area for swimming. The famous Venetian Nights were held on the lake and young people played tennis, volleyball and similar sports on the beach. The current name of the Sunny Lakes was changed in 1960, with the announcement of a contest for a new name for this natural swimming pool.

With the gradual development of the lakes, they have become a favourite holiday destination for visitors not only from Slovakia, but also from all over Europe and every year there are visitors from overseas as well.
