ROCKLAND — The public may have opportunities this summer to tour inside the historic Rockland Breakwater Lighthouse.

The lighthouse has not been opened to the public for the past few years.

The tentative lighthouse open house dates are all Sundays — July 10, July 24, Aug. 7, Aug. 21 and Sept. 4. The open houses run from 10 a.m. to 4 p.m.

Volunteers are needed, Mayor Ed Glaser said. There will be two, three-hour shifts.
