The large limestone façade of the Nassau County Court House dominates the stretch of Old Country Road between County Seat Drive and Washington Ave. Constructed in 1940, the three-story Court House houses 17 judges and county courtrooms on the first and third floors. The Court House also is home to the offices of the Nassau County District Attorney and Clerk of the Court, which occupy the second floor of the Northern and Southern halves of the building, respectively. The Northern half of the third floor is also home to the Surrogate's Court. In the center of the Court House lies the Great Hall, a skylight enclosed space with various displays including copies of both the U.S. and New York State Constitutions, a tribute to fallen officers of the September 11 attacks, and a large glass-enclosed map of Long Island and the surrounding area.
The Suffolk County District Attorney, Thomas J. Spota, has offices in five different locations throughout the county with headquarters in Hauppauge. The Riverhead office is located in the Arthur M. Cromarty Court Complex and contains the following bureaus: homicide, major crime, child abuse and domestic violence, appeals and narcotics. Spota, a Democrat, has held the elected position since 2001 and last ran in 2009, unopposed.
Six people work at this office, which is responsible for managing all of the property owned by Nassau County. The office is a "shared services" operation, coordinating the logistics and assisting in any movement of county employees and offices within Nassau from one place to another.
