With Illumination Night, the Agricultural Fair and Oak Bluffs fireworks all on the docket, this week marks the high point of traditional summer events on Martha’s Vineyard.

It all begins at sundown tonight, when the gingerbread houses of the Camp Ground will glow with the light of thousands of lanterns a part of a summertime tradition in Oak Bluffs that dates to the late 19th century.

This year marks the 150th Grand Illumination.

A community sing begins at 7:30 p.m. at the Tabernacle, followed by the ceremonial lighting of the first lantern at dusk.

Cottagers will gather on their porches in a spirit of open hospitality that has long been a hallmark of the evening.

The Grand Illumination began a year after the Camp Meeting incorporated. Today the Camp Ground, tucked just off the bustling downtown area, is listed on the National Register of Historic Places.

Large crowds are expected, parking is limited and public transportation is encouraged.

Tomorrow the 158th Martha’s Vineyard Agricultural Fair will begin its four-day run on the grounds of the Martha’s Vineyard Agricultural Society in West Tisbury.

Carnival rides, sheep and dog judging competitions, local booths and a hall filled with more than 7,000 entries from the Vineyard’s rural community of farmers, growers, bakers and quilters are all part of the scene.

The fair runs through Sunday and is a zero-waste event. Only compostable materials will be used and fair-goers are encouraged to bring their own water bottles. Water filling stations will be available and reusable cups will be sold as well.

Friday night the annual Oak Bluffs fireworks display will cap the week of summer traditions. The fireworks are hosted by the town and thee Oak Bluffs firemen’s civic association. Donations are always needed.

Fireworks go off at dusk.
