The Poland Spring Bottling Plant and Spring House is an historic water pumping and treatment facility in Poland, Maine. Built in 1907, these two buildings are the original spring house and water spa of the Poland Spring Resort, whose waters are still bottled under the Poland Spring brand name. The resort was the largest and most successful of Maine's inland summer resorts. The buildings were listed on the National Register of Historic Places in 1984; the spring house now houses the Poland Spring Museum and Environmental Education Center. Open seasonally, its exhibits feature the history of the company and its bottling operation, including scientific displays and vintage memorabilia.
