- In 1991, Johnsonburg was placed on the State and National Register of Historic Places. The significance of Johnsonburg is it was the first county seat of then newly formed Sussex County in 1753, then known as Logg Gaol. In 1753 this township was known as Hardwick Township and much of Hardwick township history is encompassed this town. Logg Gaol was county seat until 1761 when it was then moved to present day Newton. In 1825, Warren county was formed and Hardwick township became part of Warren County. In 1848, present day Frelinghuysen Township separated from Hardwick. Johnsonburg has remained the same since formed from the colonial days of Britsh rule. Many of the settlers homes still stand today, 2023 as a reminder of days gone by.
