Major excavations on Spike Island have uncovered a tunnel and a previously unknown crafted spiral staircase which are believed to have been part of a fort built there in the 1790s.

Further excavations are planned on the island in the coming days and weeks as experts believe only about 30% - 40% of the underground fortifications are currently accessible.
