Text in English & German. In the area along the Weser, there was a great deal of building activity between the Reformation and the Thirty Years War which was helped along by economic prosperity. Little affected later by war or modernisation, high quality Renaissance castles, aristocratic estates, town halls and civic architecture have survived here in exceptional density. This facet of Central European Renaissance architecture started to be appreciated in the early 20th century. This led to the concept of the Weser Renaissance, oriented above all towards formal and regional history, and still popular today, like a kind of brand. The present volume offers a representative selection of the region's castles and palaces for the first time, dealing with both princely residences and seats of the nobility. Architecture and court culture are placed in a European context that goes beyond older approaches based on the stylistic history and shows that forms demonstrating princely prestige have qualities in common well outside the region. Michael Bischoffs introductory text provides an overview of Renaissance architecture in the Weser area. Uwe Albrecht and Julian Jachmann explain the terminology and function of princely architecture. Heiner Borggrefe analyses early Renaissance architectural ornamentation, G Ulrich Großmann covers the topic after the mid-16th century. Thomas Fusenig writes on the arts and sciences at the courts. Rolf Schönlau discusses aspects of building materials in terms of economic history. Hillert Ibbeken deals with the sandstone that is most frequently used from a geological point of view. The descriptive catalogue is by Katja Schoene and Michael Bischoff.
