Focus on Shift (sculpture) and explore the History.
In the summer of 1970 Serra and artist Joan Jonas visited the site, a 13-acre potato farm in King Township. They discovered that if two people walked the distance of the land towards each other while keeping each other in view, they had to negotiate the contours of the land and walked in a zigzagged path. This determined the topographical definition of the space and the finished work would be the maximum distance two people could occupy while still in view of one another. The sculpture's construction began in 1970 and ended in 1972.In 1973 Serra discussed Shift in Art in America:What I wanted was a dialectic between one's perception of the place in totality and one's relation to the field as walked. The result is a way of measuring oneself against the indeterminancy of the land. As one follows the work farther into the field, one is forced to shift and turn with the work and look back across the elevational drop. From the top of the hill, looking back across he valley, images and thoughts are remembered which were initiated by the consciousness of having experienced them.
The land was owned by the family of Roger Davidson, an art collector. Serra approached Davidson with an idea to use the land for a site-specific sculpture. Davidson agreed in exchange for two of Serra's smaller sculptures. Ownership of the work was undetermined and as there was no contract, Serra understood that the work would be preserved on the land by the Davidson family and that the land would not be sold and would be accessible to the public.In 1974, the land, registered in Davidson's mother's name, was sold to Hickory Hill Investments, a land developer. Land registry records made no mention of an artwork on the property.  The Ontario government listed the land as protected under the Oak Ridges Moraine Conservation Act as a green space, while Shift is protected under Canadian copyright law as Serra is a landowner in Nova Scotia. The Toronto-based developer announced in 2010 planned to develop the property for housing. Shift and the surrounding land was designated a protected cultural landscape under the Ontario Heritage Act. In 2013 the Township of King voted to prepare a bylaw to designate Shift as protected under the Ontario Heritage Act, preventing its destruction or alteration.
