The Henry County Courthouse is a historic courthouse located in New Castle, Henry County, Indiana, US, on the land designated as court house square by the Henry County Commissioners. The Court House was built between 1865 and 1869 at a cost of $120,000. An annex was added in 1905 at a cost of $44,000.When it was built the commissioners wanted a fireproof courthouse. They did not want to see the courthouse burn again as it had in 1865. Architect Isaac Hodgson provided them with what they wanted, but with a mansard roof and a 110-foot clock tower. The mansard roof was unusual for a midwestern public building in the 1860s. It became popular later, but the Henry County Court House was probably the earliest example of the style for public buildings in the midwest.Henry County claims the distinction of being the Raintree County described in Ross Lockridge Jr.'s book Raintree County in part because the Henry County Court House is pictured inside the front cover of the book and the book includes references to places in Henry County. It was added to the National Register of Historic Places in 1981. It is located in the New Castle Commercial Historic District.

New Castle High School is a public high school in New Castle, Indiana whose name is commonly abbreviated to NCHS. It is part of the New Castle Community School Corporation and has an enrollment of approximately 900 students. NCHS is the largest high school in Henry County. The present high school originated from the New Castle Academy in 1870. In 1895, New Castle High School was constructed. Because of its distinctive appearance, the building became known as "The Castle." In response to a significant increase in enrollment, a new senior high school was constructed in 1923–24 at 14th and Walnut Streets. Plans to construct an additional wing and a multi-purpose facility were never developed. Instead, physical education classes were conducted at the National Guard Armory across the street and basketball games were played at the YMCA in the "Church Street Gym." The Walnut Street location served as the senior high school until 1958 when the present high school facility was completed. The 1924 structure then joined the 1895 "Castle" building as a junior high school. In 1973, eighth and ninth grade students began attending the newly constructed Parkview Junior High School. The "Castle" was subsequently demolished, and the Walnut Street school exclusively housed seventh grade students until 1999. The location was home to the Raintree Education Center until 2010; the building was sold to a private owner in 2011.
