Experience a bit of Downton Abbey at The Crane Estate on Boston's north shore. This popular National Historic Landmark gives visitors a taste of the 1920's and all its opulence. The Grande Allée, the only one in the country, is a 1/2 mile stretch of undulating emerald grass that stretches down to the ocean. A recently completed Casino Complex is the crown jewel of the elaborate Italianate gardens. Visitors can take a self guided tour in the mansion where interactive exhibits share tales of the family. Check the calendar for special events; summer cocktail nights are a great way to enjoy another era and walk back in time.
