U.S. Naval Radio Station Otter Cliffs was a United States Navy radio receiver facility located in Acadia National Park on Mount Desert Island, south of Bar Harbor, Maine. The station was commissioned on August 28, 1917, under the command of Lt. Alessandro Fabbri, who had personally cleared the land, built and equipped the station, and offered it to the government in exchange for a commission in the Naval Reserve and assignment as Officer-in-Charge. Prior to the war, Fabbri was a licensed radio amateur with the U.S. Government issued call sign 1AJ. Otter Cliffs was the Navy's best transatlantic radio receiver site because of its absence of nearby man-made radio noise, its unobstructed ocean path from Europe, and the outstanding receivers, antennas and noise mitigation techniques developed by the Wireless Specialty Apparatus Company under the leadership of Greenleaf Whittier Pickard. Pickard is well known for his early inventions in connection with loop aerials, direction-finding systems and static mitigating devices used at Otter Cliffs during the war. His technical achievements and illustrations of equipment at Otter Cliffs during the war were documented in detail in the Proceedings of the IRE. Edmond Bruce, a Navy enlisted man, served as chief electrician for the transatlantic receiver during the war. He later became a widely recognized radio engineer and inventor. By the end of the war, more than 100 Navy enlisted men and 25 Marines were assigned to the station. By 1933, however, its buildings had become dilapidated and Navy funds were not forthcoming for repairs. When John D. Rockefeller Jr. suggested that it be removed, the Navy agreed to include the station in his donation to Acadia National Park, provided that he would build an equally good receiving station nearby. He did so at the tip of the Schoodic Peninsula, about five miles away across Frenchman Bay, and Feb. 28, 1935 Otter Cliffs was decommissioned and the new Winter Harbor station was commissioned. (It later became Naval Security Group Activity, Winter Harbor, and on July 1, 2002, was decommissioned and transferred to the National Park Service.)

Wildwood Stables is a farm near Seal Harbor on Mount Desert Island, Maine, United States. Located in Acadia National Park, on the Park Loop Road, the farm (originally known as Wildwood Farm) was established in 1911. Only the original barn is now standing, after the National Park Service demolished the farm's other structures in 1958. Today, Wildwood Stables is home to several horses which pull carriages around the park's carriage trails in the spring, summer and fall months.

Birdsacre Sanctuary, also known as Stanwood Wildlife Sanctuary, is an historic house museum and wildlife sanctuary at 289 High Street in Ellsworth, Maine, United States. The core of the property is a 40-acre (16 ha) parcel owned by the pioneering Maine ornithologist Cordelia Stanwood, whose home was opened as a museum in 1960, and is listed on the National Register of Historic Places in 1973. Stanwood's homestead was extensively damaged by an arsonist-set fire in 2014. The sanctuary, now 200 acres (81 ha), includes trails, an orchard, and a nature center that showcases a fine art and nature collection, including Cordelia J. Stanwood's avian field-notes and extensive photographic collection.

Acadia National Park is an American national park located along the mid-section of the Maine coast, southwest of Bar Harbor. The park includes about half of Mount Desert Island, part of the Isle au Haut, the tip of the Schoodic Peninsula, and portions of sixteen smaller outlying islands. The park contains the tallest mountain on the Atlantic Coast of the United States (Cadillac Mountain), exposed granite domes, glacial erratics, U-shaped valleys, and cobble beaches. Its mountains, lakes, streams, wetlands, forests, meadows, and coastlines contribute to a diversity of plants and animals. Woven into this landscape is a historic carriage road system financed by John D. Rockefeller Jr. In total, it encompasses 49,075 acres (19,860 ha; 76.680 sq mi; 198.60 km2) as of 2017. Acadia has a rich human history, dating back more than 10,000 years ago with the Wabanaki people. The 17th century brought fur traders and other European explorers, while the 19th century saw an influx of summer visitors, then wealthy families. Many conservation-minded citizens, among them George B. Dorr (the "Father of Acadia National Park"), worked to establish this first U.S. national park east of the Mississippi River and the only one in the Northeastern United States. Acadia was initially designated Sieur de Monts National Monument by proclamation of President Woodrow Wilson in 1916, then renamed and redesignated Lafayette National Park in 1919. The park was renamed Acadia National Park in 1929. Recreational activities from spring through autumn include car and bus touring along the Park Loop Road; hiking, bicycling, and horseback riding on carriage roads (motor vehicles are prohibited); fishing; rock climbing; kayaking and canoeing on lakes and ponds; swimming at Sand Beach and Echo Lake; sea kayaking and guided boat tours on the ocean; and various ranger-led programs. Winter activities include cross-country skiing, snowshoeing, snowmobiling, and ice fishing. Two campgrounds are located on Mount Desert Island, another campground is on the Schoodic Peninsula, and five lean-to sites are on Isle au Haut. The main visitor center is at Hulls Cove, northwest of Bar Harbor. Park visitation has been steadily increasing in Acadia over the past decade, with 2021 seeing a record count of 4.07 million visitors.

Acadia National Park, largely on Mount Desert Island, off the coast of the U.S. state of Maine, was created in part by land and other donations by John D. Rockefeller Jr. Between 1919 and 1931, Rockefeller, who was opposed to the introduction of automobiles on the island, personally oversaw the construction of a network of carriage roads, closed to motorized vehicles, on the eastern half of the island, including sixteen granite bridges and two gatehouses. The major portion of this network now falls within the bounds of the national park, and was listed on the National Register of Historic Places in 1979. The network of carriage roads is open to the public for non-motorized uses in the summer, including walking and bicycling. In the winter, most of the network is open to cross-country skiing, and a portion of it is open to snowmobiling.

Stanley Brook Bridge is a bridge in Acadia National Park, Maine. Spanning Stanley Brook carriage trail and Stanley Brook itself in Seal Harbor, it was built in 1933. It was the last bridge designed and constructed in the park under the guidance of John D. Rockefeller Jr.The bridge, which is constructed of ashlar stone, was designed by Charles Stoughton and built by S. F. Ralston, superintendent of Rockefeller's Seal Harbor estate. Landscape architect Beatrix Ferrand planted fauna around the bridge. At 180 feet (55 m) in the length, the bridge has three spans: the western one passes over Stanley Brook; the central one crosses Stanley Brook Road; and the eastern span is over a footpath.

Saint Jude's Episcopal Church is a historic church at 277 Peabody Drive (Maine State Route 3) in Seal Harbor, Maine. Built in 1887–89, this Shingle-style church is the least-altered surviving example of ecclesiastical architecture in Maine designed by the noted exponent of the style, William Ralph Emerson. Principally used as a summer chapel, it is affiliated with the Episcopal mission of St. Mary's in Northeast Harbor. The building was listed on the National Register of Historic Places in 1986.

Cadillac Mountain is located on Mount Desert Island, within Acadia National Park, in the U.S. state of Maine. With an elevation of 1,530 feet (470 meters), its summit is the highest point in Hancock County and the highest within 25 miles (40 km) of the Atlantic shoreline of the North American continent between the Cape Breton Highlands, Nova Scotia, and peaks in Mexico. It is known as the first place in the continental U.S. to see the sunrise, although that is only true for a portion of the year.

The former Seal Harbor Congregational Church is a historic church building on Peabody Drive (Maine State Route 3) in Seal Harbor, Maine. It was built in 1902, and is an elegant expression of the Shingle style in a seasonal church building. It was listed on the National Register of Historic Places in 1985; it is now vacant.

The Eyrie Summer Home was the summer residence located in Seal Harbor, Maine of the Rockefeller family. It was purchased by John D. Rockefeller Jr. in 1910. Rockefeller hired architect Duncan Candler to oversee the original cottage's expansion in 1914. The current location is home to the Abby Aldrich Rockefeller Garden.

Highseas is a historic early 20th-century summer estate in Bar Harbor, Maine. It is located on Schooner Head Road on the east side of Mount Desert Island, surrounded by the lands of Acadia National Park. Built in 1912, it is one of the few grand summer estates to survive the island's devastating 1947 fire. It is now owned by the Jackson Laboratory and used as housing for students enrolled in its prestigious Summer Student Program. The property was listed on the National Register of Historic Places in 1978.

Ellsworth City Hall is the seat of local government in Ellsworth, Maine. Built in 1934-35 after a devastating fire destroyed the old city hall and part of the business district, it is a municipal building with Georgian Revival features unusual for Maine. The building was designed by Philadelphia architect Edmund Gilchrist, and is reflective of that area. The building was listed on the National Register of Historic Places in 1986.
