In a lecture called “1969: The Year That Pointed the Way” on Monday at 5:30 p.m. at the Rogers Memorial Library, Clive Young, an author, will explore the moon landing, Woodstock, the distinctive music of the time, and fashion trends.

Tony Garro of the Southampton Trails Preservation Society will lead a tour of the Beebe Windmill off Ocean Road on Saturday from 11 a.m. to 1 p.m.

Also on Saturday, the Bridgehampton Museum’s Corwith House on Main Street will be open from 10 to 2 to show off its summer exhibition, “Building a History: The Preservation of the Nathaniel Rogers House,” which chronicles the various owners of the 19th-century Greek Revival mansion on the corner of Ocean Road and Montauk Highway.

There’s a lot to be learned from the old one-room schoolhouses that are scattered across the East End. Some have become museums or civic meetinghouses, while others simply stand as landmarks of bygone eras, and at least one, in Sagaponack, is still in use as a school. While their sizes and shapes varied, most of the one-room schoolhouses shared a common element: They were in communities that built anew whenever a tragedy such as a fire ravaged a schoolhouse or when the local population of children simply outgrew the existing space. These are some that stand out.
