Owned By: Union Point

The South Field Dog Park is located in a sunny spot within the Union Point development, on the site of the former South Weymouth Naval Air Station. There are 2 fenced-in areas — one for medium-sized dogs and one for larger dogs — plus some wooden ramps and climbing structures. The South Field Playground and Shea Memorial Grove are right next door. Also an access point for the Union Point Northern Gateway Trail Network.


Some history: Naval Air Station South (NAS) Weymouth was commissioned on this site in March 1942, however construction work began in the late fall of 1941, a few months before the United States entered World War II. Originally the base operated blimp combat patrols. During the Battle of the Atlantic, blimps based here helped protect U.S. ships from German submarines.

The base was downgraded to a Naval Air Facility after WWII. The blimp hangars were repurposed as storage for war surplus naval aircraft. In 1949, the base was redesigned as a Naval Auxiliary Landing Field. In 1950, after the closure of NAS Squantum in Quincy, South Weymouth became the new home of the Navy and Marine Air Reserve training program. Between 1951 and 1953, three new runways were constructed, and other improvements were made to support the reserves. One blimp hangar was demolished at this time. The other remained in place until November 1966.

In December 1953 the base was recommissioned as a Naval Air Station. It remained a reserve training base throughout the Cold War era, and also hosted the Naval Air Development Unit (NADU), a secretive research & development command. NADU aircraft provided flight testing support for military research.

After the end of the Cold War in 1991, NAS South Weymouth was among many military bases nationwide that were selected for closure. The last aircraft took off from the base in September 1996, and the official closure took place on September 30, 1997.

The former Naval Air Station is now being developed as Union Point, with a variety of uses. The transformation is far from complete, which makes this a fascinating place to visit. Old barracks, bunkers, and other buildings, plus fences, roads and gates offer glimpses of the military past. Please be mindful of private property.

This land is within the region of the Massachusett (or Massachuseuk). To learn more about local Native American tribes, we encourage you to interact with their members. The Mattakeeset band of the Massachusett, and the Massachusett tribe at Ponkapoag, both share information on their websites.

Habitats and Wildlife

The park is located in an open field, with a small playground right next door. Nearby are some wetlands and relatively young woodlands with pine, oak, beech, red maple and white birch. The property is located within the watershed of the Weymouth Back River. Its waters flow northeast toward Whitman’s Pond and the Weymouth Back River. The Weymouth Back River flows for about 10 miles, and empties into the Atlantic Ocean at Hingham Bay, just south of Grape Island and Slate Island.
