The Poland Spring Preservation Society was formed to preserve the Maine State Building and the All Souls Chapel. The Maine State Building was created in 1893 for the Chicago World's Fair. At the fair, it displayed exhibits, portraits of famous Maine residents, taxidermy, and a library. At this point in time, the building houses a portion of its original contents, as well as exhibits of local artwork. The Catholic and Protestant chapel was completed in 1912.

The society offers exhibits, an art gallery, and summer concerts.

The Museum tells the stories of 97 Orchard Street. Built on Manhattan's Lower East Side in 1863, this tenement apartment building was home to nearly 7,000 working class immigrants. They faced challenges people understand today: making a new life, working for a better future, starting a family with limited means. In recognizing the importance of this seemingly ordinary building, the Tenement Museum has reimagined the role that museums can play in modern lives.

The museum offers exhibits, tours, educational programs, and educational and recreational events.

St. Ignatius Mission is an 1890s religious structure located in the present-day Flathead Indian Reservation. The mission contains 61 paintings by one of its brothers.

Santa Cruz Mission State Historic Park is the site of a complex of buildings erected around the original Santa Cruz Mission. Part of the cluster, the Neary-Rodriguez Adobe was built in 1791 and is the last of the mission's many buildings to survive. The single-story adobe has been restored to its original appearance. Misión la Exaltacion de la Santa Cruz was the 12th mission built in California. It was completed during the 1790s. Damaged by several earthquakes, it collapsed in 1857.

The park offers exhibits; tours; and occasional educational and recreational events, including living history events.

The Jemez State Monument Heritage Area includes the stone ruins of a 500-year-old Indian village and the San José de los Jemez church dating to 1610. The village of Giusewa was built in the narrow San Diego Canyon by the ancestors of the present-day people of Jemez (walatowa) Pueblo. The name Giusewa refers to the natural springs in the area. In the 17th century, the Spanish established a Catholic mission at the village. The mission was short-lived, and, in time, the people abandoned the site and moved to the current location of Jemez Pueblo. The massive stone walls were constructed about the same time the Pilgrims landed at Plymouth Rock. The heritage center contains exhibitions that tell the story of the site through the words of the Jemez people. A 1,400-foot interpretive trail winds through the impressive site ruins.

The site offers exhibits.
