Lunenburg Academy, built between 1893 - 1895, is a massive, three-storey wooden Victorian building in the eclectic tradition, boldly painted in red, black and white in the town of Lunenburg, NS. The Academy continuously functioned as a public school (P-12) and later (P-6) from 1895 until 2012 when it closed with the opening of Bluenose Academy.

Located high atop Gallows Hill, the school is visible from most viewpoints when approaching Lunenburg and is colloquially referred to as 'the Castle on the Hill'. At night, the building could be mistaken for a castle as it is flooded with light by four massive spotlights. On foggy nights, this diffuse light creates an eerie ambience around the building surrounded as it is by cemetery on three sides.

The Heritage Interpretive Classroom is a newly built interpretive centre which tells the story of the Academy, it's place in the history of the town, and significant educational reform which was happening during this era.

Architecturally, Lunenburg Academy it is described as an ornate Second Empire style Academy building.  It was was registered as both a Provincial Heritage Property and a National Historic Site in 1983. This Heritage designation which covers the building and surrounding property, abuts Lunenburg's Old Town Heritage Conservation District. The building is now the only intact 19th century Academy Building surviving in Nova Scotia and one of the few remaining Public Schools of the 19th Century.

The heritage value of the Lunenburg Academy lies in its significance both historically and architecturally, and as both a local and national landmark. Designed by well-known New Brunswick architect H.H. Mott, and built between 1893-1895, the Academy is a monument to the historical development of Nova Scotia’s educational system. It provides an architectural example of the evolution of education in nineteenth century Nova Scotia from one-room schoolhouses to the Academy system. The Academy is one of very few large scale wooden buildings in Canada still surviving from the nineteenth century. Its unique and picturesque design makes it an excellent representation of late Victorian eclectic architecture. Many interior features also remain, including wainscoting, stairways and banisters, detailed hinges and doorknobs, and the layout of classrooms and cloakrooms.
