Archaeological testing Dundalk

Geophysical survey of a school site in Dundalk revealed a number of strong linear responses which were investigated with a number of test trenches. A very large drainage channel ran diagonally across the site corresponding with a feature shown as “Ship Canal” on historic mapping (Brownrigg). The channel was 4m wide and 1.5m deep filled with stone, red brick and assorted refuse. Some nice finds came out of the trenches including a bone chess piece believed to be a Calvert Chess piece. This elaborate early 1800s English chess design, referred to as a Calvert Pattern,  is derived from earlier German designs from the 15th through the 19th centuries.
