Description: The building faces south and is a four story red colored brick, concrete and glass structure. The building is located on landscaped grounds in the center of Williamsport. All sides of the square shaped building are the same. The first story is all glass and recessed. The rest is covered with a smooth glassy brick and a black colored window treatment that varies at the top to break the monotony. The roof line is flat. There is a newer county office building directly behind, also in modern office building style.
History: The county was created in 1795 and Williamsport was selected as the county seat. The first courthouse was built by John Turk and Edward Gobin in 1802 to 1804 using the plans of the courthouse in Dauphin County, and the plans were used again to build the courthouse in Lehigh County. The second courthouse was designed by Samuel Sloan and constructed by D S Rissell in 1860. In 1903 an addition was designed by Truman P Reltmeyer. The plans for this courthouse were used to build the courthouse in Northumberland County. The third and present courthouse was constructed in 1969 to 1970.
