Another source that I have found to be very knowledgeable about Monadnock is Kerry, He posts here as Kerry13.
I hope I didn't put Kerry on the spot but he has helped me with questions in the past.
Doric was a type of Greek architecture incorporating large fluted columns. I haven't found anything there, as of yet, that would jump out as being Doric type architecture.
I agree, is this the place Andrew was talking about?
Just read Kerry113's reply. Thanks. I had looked at the link that you sent. All very interesting to consider. To my way of thinking, something named the Doric Temple should have some columns, but unless someone was into carving fluted columns, we probably won't find it. Maybe, they just used artistic license in naming the area.
