洛克兰县的历史可以追溯至几个世纪以前，美国原住民最先定居于此，之后荷兰和英国移民也纷至沓来。这里也是 18 世纪末期美国独立战争的主战场之一。在洛克兰县 19 世纪和 20 世纪的历史发展过程中，农业、制造业和宗教占有非常重要的地位。.
名胜古迹包括美国独立战争期间的两个重要地点：石点战场国家历史遗址 (Stony Point Battlefield State Historic Site) 和石点灯塔 (Stony Point Lighthouse)，以及 DeWint House，这些在战时都曾是乔治·华盛顿的指挥部所在地。探访 18 世纪和 19 世纪建造的几所古宅，例如Jacob Blauvelt Farmhouse、Salyer House 和 DePew House，美国独立战争那段时间美国人早期的生活方式依稀可见。哈弗斯特劳砖博物馆 (Haverstraw Brick Museum) 和萨菲恩铁路博物馆 (Suffern Railroad Museum) 等小型博物馆折射出工业时代的影响。
Rockland County has a history that goes back centuries, to the Native Americans who first settled here, followed by Dutch and British settlers. This was also the site of important battles in the American Revolutionary War in the late 18th century. Agriculture, manufacturing, and religion all played a prominent part of Rockland County’s history in the 19th and 20th centuries.
Historic sites of interest include two important Revolutionary War locations: the Stony Point Battlefield State Historic Site and Stony Point Lighthouse, and the DeWint House, which once served as George Washington’s headquarters. Several historic homes built in the 18th and 19th centuries, such as the Jacob Blauvelt Farmhouse, Salyer House, and DePew House portray how early Americans lived around the time of the Revolutionary War. Smaller museums highlight the impact of the industrial age, such as the Haverstraw Brick Museum and the Suffern Railroad Museum.
