For Denver’s Wellington E. Webb Municipal Building, RNL’s landscape architecture studio worked with international artists Larry Kirkland and Robert Murase on the main entry plaza facing Civic Center Park. The centerpiece is a Double Head Sculpture, facing east and west, symbolizing Denver’s past and its future. Between the heads hangs a surveyor’s plumb bob, signifying “plumbing the depths of the mind;” the plaza’s granite paving circulates the plumb bob in the form of a surveyor’s target. The plaza design positions the City of Denver in the larger world, with its geographic position represented by two wide, bi-axial granite bands suggesting longitude and latitude, crossing beneath the head sculpture.
