ABSTRACT
After decades of research, the existence of an enclosure idea in prehistoric Europe is widely accepted nowadays (e.g., Andersen 1997; Burgess et al. 1988; Darvill and Thomas 2001; Gibson 2002; Jorge 2003a; Márquez-Romero and Jiménez-Jáimez 2010; Valera and Evangelista 2010; Varndell and Topping 2002). However, a good number of key issues remain under discussion. The following was originally brought up by Evans (1988) and recently revisited by Whittle (2006: 21): were prehistoric enclosures built with a preconceived plan in mind? Were their particular layouts predesigned?
