Wondering about the history or residents of this Somerville Avenue Cemetery? Come learn more from volunteer docents dressed in historic period clothing this weekend. The small historic site, established in 1804, is usually closed to the public except for two annual events in May and October. On Sunday, July 13 and Monday, July 14, volunteers will be on hand at the site for any interested community members to learn about the Somerville residents buried at Milk Row. The Cemetery will be open on Sunday from 1 to 3 p.m., and Monday from 6 to 8 p.m.
