Fort Philip (also spelled Fort Phillips) was a fort built in 1776 during the American Revolutionary War and rebuilt in 1808, which also served in the War of 1812 to around 1815. It was in Newburyport, Massachusetts on the northern end of Plum Island, known as Lighthouse Point, guarding the mouth of the Merrimack River. The 1808 rebuilding was part of the second system of US fortifications. The secretary of war's report on fortifications in December 1808 states that "...a battery of wood, filled in with sand and surmounted with sod, has been erected. It... was constructed of wood on account of the shifting sands." A subsequent report in December 1811 describes the fort as "...an enclosed battery, built of earth and timber, mounting five heavy guns... ." The site eventually washed away in the 1830s. A militia artillery battery was stationed in the area in the Spanish–American War.

The Fort at Salisbury Point was a fort in use from 1863 to 1865 in Salisbury, Massachusetts, during the American Civil War. It was also called the Fort at Salisbury Beach. It was a nine-gun earthwork located at the mouth of the Merrimack River at what is now the Salisbury Beach State Reservation, where eventual erosion washed it away. A 1903 reference states it was on the site of the Revolutionary War Fort Nichols, but that site is in doubt, and may have been at the location called Salisbury Point in Amesbury, several miles up the river. The Fort at Salisbury Point was sometimes referred to by local civilians as Fort Nichols in the Civil War era. The fort was designed and built under the supervision of Major Charles E. Blunt of the United States Army Corps of Engineers. An armament report dated June 30, 1866 lists nine heavy guns and one 12-pounder field gun. The heavy guns were three 8-inch smoothbore Rodman guns, three 42-pounder rifled guns, and three 30-pounder rifled guns. From November 1864 to June 1865 it was garrisoned by the 20th Unattached Company of Massachusetts militia. The Museum at Salisbury Point commemorates the soldiers who fought in the war.

Ann's Diner (now known as Pat's Diner) is a historic diner at 11 Bridge Road (US Route 1) in Salisbury, Massachusetts, United States. The diner was built in 1950 as #824 by the Worcester Lunch Car Company, as a custom job for James and Ann Evans. They had opened their first diner in Haverhill, also called Ann's Diner, in 1948, and moved it to the present site later that year. The business was successful enough that they ordered the present diner as a replacement. It was specifically designed to accommodate a separate dining room, and was opened in April 1950. The Evanses owned the business until 1960, after which it went through a succession of owners. From 1976 to 1987 it was owned by Norman Brockelbank and known as Norm's Place. The diner was closed between 1997 and 1999. In 1999 it was acquired by Pat Archambault, who restored it and reopened it as Pat's Diner.The diner is a classic barrel-roof diner, nine window bays long and three deep.

The right side door retains its original steel door with sunburst motif, and the middle bay window on the front facade has been replaced by an entrance that projects from the diner's body. The barrel roof is covered by a rubber membrane, and extends to porches that covered the entrances at the ends.Behind the diner body is a wood frame single story structure, which houses the kitchen and restrooms.
