Świdermajer Style is unique to the area of Otwock - a summer destination on the outskirts of Warsaw, Poland. The style is named after Świder - a picturesque river that flows through this region. Characteristic, light wooden constructions with rich ornamental detail fit perfectly into the landscape of forested banks and sandy beaches.

The place was favoured by notables from the arts and science community in Warsaw. Many artists, writers or doctors had their summer houses in the area. Also, leaders of different religions had their residences here. Otwock was especially popular among the Jewish population - before the 2nd World War, at least a few Hasidic leaders had lived here permanently.  In 1936, a part of the then most eminent yeshiva was moved from Warsaw to a wooden villa that still exists today.

The architecture of these wooden villas, called by locals Świdermajery, is one of a kind and by many historians and architects treated as a separate style. The truth is, it is a very skilful mixture of three different styles: a local Masovian style, the Swiss Alps chalets, as well as the cottages of Tsarist Russia. This surprising combination makes these buildings one of the most important elements of the region's heritage.
