Don't know a Greek Revival from a Gothic Revival? A First Period from a Second Empire? Have no fear, the Boston Globe Magazine has put together a field guide to local architecture for "Boston and its environs." (Yes, in this case, the Cape and Islands count as environs of Beantown.) The article has the low-down on architectural style vs. type, tips for identifying building styles and a handy guide for finding old supplies. [Boston Globe Magazine]
