Fort Wentworth

Fort Wentworth was a colonial fort built in 1755 at the junction of the Upper Ammonoosuc River and Connecticut River, in Northumberland, New Hampshire, just downstream from the present site of Groveton.

Paper mill

Diamond International Papers was originally the hub of Groveton. Diamond International was replaced by James River Paper Company, which was followed by Wausau Paper. In 2008 Wausau ceased production in its Groveton mill, which in turn precluded the trains from stopping in Groveton.

There were plans to turn the mill into a biomass plant, but as of January 2012, plans for buying the mill had fallen through.[3] After an interview with former mill employees, the town of Northumberland decided to demolish the mill for scrap metals. With the price of metals at an all-time high, the town would make more money with the metals than waiting for the mill to sell. Plans for the future site included an LNG plant, which would have brought 80 or so jobs to the North Country. However, the planned development did not materialize.

Hydrogen power plant

Q Hydrogen,[4] in conjunction with state and local political and development officials, is a developer of a hydrogen production system using water.

Electricity production has begun at the site of the old paper mill, which has been scraped clean of most evidence that the 140-acre (57 ha) facility existed there.[5]

Steam locomotive

A coal-powered steam locomotive originally owned by the Odell Manufacturing Company paper mill is publicly displayed as a tourist attraction. Having last seen use in the mid-1960s, it is presently maintained by Wausau Mills and Groveton Paper Board. The community beautification committee "dresses it up" every Christmas and maintains the surrounding area.

Riverside Speedway and Adventure Park

In 1964, Riverside Speedway, a 1/4 mile banked oval track, opened in Groveton. In late 2014 the speedway was purchased and underwent a name change. It was sold again in late 2019 and renamed Riverside Speedway and Adventure Park. In the coming years upgrades are planned for the facility to be a four-season event location, including ATV/UTV and other off-road events as well as snow machine racing. It features weekly racing series and is a popular venue in local auto racing.

The Early Show

Groveton was featured on The Early Show on January 5, 2012. It was a story on the mill and featured Karen Brown of The Early Show and Roger Caron.
