Construction is set to begin later this season on the City Bicentennial Monument. The project will include a fully functional Sun Dial will walk you through 20 decades of Rochester’s history, spanning 200 years. Each decade stone will have a bronze plaque defining a moment in Rochester’s history. Twenty decade stones are available for sponsorship. Sponsors’ names will be cast in a plaque. The large Gnomon (dial) will also be available to sponsor.
