New Hampshire ? A massive fire damaged or destroyed dozens of wood-frame buildings, mostly unoccupied summer homes, at a 146-year-old Christian center on Easter.

The fire erupted at 4:30 p.m. on Sunday, when Christians were celebrating the resurrection of Jesus Christ. But the season hadn’t begun yet at the Alton Bay Christian Conference Center on Lake Winnipesaukee, and state Fire Marshal William Degnan said no injuries to residents had been reported.

It was cold and windy Sunday, and Degnan said strong gusts of up to 35 mph off the lake, the state’s biggest, helped spread the flames through the many cottage-style homes at the center, about 30 miles northeast of Concord.

Witnesses said they watched as buildings burned to the ground in minutes.
