Resort architecture or Bäder architecture (German: Bäderarchitektur) is an architectural style that is especially characteristic of spas and seaside resorts on the German Baltic coast. The style evolved since the foundation of Heiligendamm in 1793, and flourished especially around the year 1900, when resorts were connected to big cities via railway lines. Until today, many buildings on the German coasts are built in the style or feature distinct elements of resort architecture.
Single free-standing mansions featuring resort architecture are also called Bädervilla (plural Bädervillen), translating as Resort Mansion or Spa Villa. The architecture of inland health spas in Central Europe (i.e. those away from the coast), in Thuringia, the Czech Republic or Switzerland for instance, is generally referred to as spa architecture (Kurarchitektur).
The style especially received a boost with the railway lines connecting the then booming seaside resorts of Germany to European metropolitan areas in the late 19th and early 20th century. It can be a variation of several styles with new elements, including historicism and Art Nouveau, for instance. It is often characterised by two to four storey buildings whose façades are often decorated with balconies, gables and verandas. In larger villas there are occasionally central avants-corps. Arched or rectangular windows predominate, occasionally flanked by half-columns or blind pilasters. Triangular gables and occasionally also curved gables or small turrets close off the ends of the attics. What is special about this form of architecture is its basic composition in classical styles that are very freely combined and which may be mixed with art nouveau ornamentation, for instance on the capitals.
The most common colour is white, which is why the health spas are occasionally described as “white pearls”. As a result, the rare examples in colour, for example, painted in Bordeaux red, olive green, beige or blue, set amongst their white counterparts, are very striking. Overall the buildings appear rather delicate and are often built of wood with a core of stone. Among the best-known examples today are those found on the Baltic coast on the island of Rügen, for instance in Sellin, Binz or Göhren. Heiligendamm near Bad Doberan is the oldest German seaside spa; numerous buildings from the early spa era can be found there. Entire ensembles in white with occasionally coloured buildings are found in the parish of Heringsdorf on the island of Usedom. As well as in Kühlungsborn. One of the oldest buildings featuring the resort style was built by Georg Bernhard von Bülow in 1845 in Heringsdorf, Villa Achterkerke. One of the art-historically most important buildings (due to its glass mosaic), is the Villa Oechsler in Heringsdorf, built in 1883 by Antonio Salviati.
