Preserving Old Lahaina Prison’s Perimeter Wall
Crumbling Walls Highlight Technical Challenges THE SITE In 1851, “an Act relating to prisons, their government and discipline” was approved by King Kamehameha III and authorized a new jail in Lahaina, Maui.

In analyzing the collapse, the historic architects at MASON said, “We suspect that the two faces of the coral stone are separating due to insufficient tie stones (aka through stones or deadmen). This may have caused the walls to move out of plane and the mortar cap to split; water intrusion at the top of the wall has only exacerbated the problem. We suggest rebuilding the upper portions of the wall [...]
