Focus on this artwork and explain the Condition.
Because of the soft nature of limestone, the fountain eventually had to be renovated to replace the existing blocks which by 1998 had worn away to the point of being at risk of sliding. A limestone-colored type of granite from China was chosen as the replacement material, being a much more durable stone. Granite is also much heavier than limestone, so the foundation was recast to withstand the additional pressure. The rim of worn limestone which edged the platform was removed. With these improvements, the lifespan of the fountain was expected to gain several decades. A rededication took place following the renovation in December 1998.
