Bannerman's Castle Collapse
In December 2009, a significant portion of Bannerman's Castle's main tower collapsed. I visited with fellow ruin-enthusiast Rob Yasinsac on a bitterly cold winter day in January 2010 and got these pictures from the mainland.

An overview of Bannerman's Island after the collapse.

The north and east walls of the main castle tower have fallen, making the ruins unstable.

The lodge in front of the crumbling castle ruins remains intact.

One of the towers on the breakwater is also in danger of falling down.

Some legends say Bannerman's Island may be haunted.
There's a huge piece missing from the main tower (built in 1909), making the entire structure dangerously unstable. Every year, these structures crumble a bit more and are at risk of collapsing because there isn't enough money to preserve them. You can help by donating to the Bannerman's Castle Trust, a non-profit organization dedicated to stabilizing and maintaining the castle buildings on the island.
