I just came across some beautiful pictures [link to PowerPoint slides] of synagogues in Budapest most of which I have never seen despite it being my hometown. You will notice that they are tucked away with quite some care in several cases, which makes it easy to miss them. The photographer has many other slideshows available on his Web site.
Social scientists looking for a conference excuse to see these sights may want to consider submitting an abstract to the annual meetings of the Society for the Advancement of Socio-Economics to be held this summer in Budapest. Abstracts are due March 1, 2005.
