Woodland Bridge Removed

The Woodland Bridge sat astride the ravine in the Olmsted Woods for some 60 years. With its rustic wooden pilings and charming gazebo sited mid-span, it held memories for decades of students crossing over and countless visitors entering the woods to ascend the Pilgrim Way. 

The condition of the bridge was assessed and it was concluded that the structure was beyond repair. The structure was removed in March 2021.

Sculpture Conservation in the Bishop's Garden

The Bishop’s Garden is home to a number of 15th-century bas-reliefs and a Carolingian-era baptismal font. Time and atmospheric exposure have taken their toll on our sculpture, and these unique garden elements now require proper conservation care. In 2016, All Hallows Guild engaged conservation professionals to survey the sculpture of the garden and six artifacts have been prioritized for care. All Hallows Guild is funding this project at a cost of $20,000, and the conservation work will run October 1 through October 12, 2018.
