The porch, seen here in a picture from the first half of the last century, is one of many discoveries made by the three archaeological studies in the last 15 years. The studies have uncovered evidence of Indian occupation of the area pre-dating European colonization as well as hundreds of artifacts from the colonial and more recent periods. The house is the last remaining Colonial country estate in Jamaica Plain.
