Curbed reports, via SocketSite, that Albion Castle, the former Albion Porter Ale Brewery in Hunters Point, is up for sale again. The castle is a historic building featuring 200-foot deep caverns that lead to a natural springs next door. It used to be the home of Laughing Squid’s web hosting tech support center and was host to their blog launch party in 2005 (which we still kick ourselves for not attending), soon before it sold for $2.1 million. The castle has been restored, and the current asking price is $2.9 million. The newest owner had planned on bringing back the brewery and opening a restaurant, which probably would have been a feat in this economy. Check out Scott Beale's photos of the castle before the restoration.
