My understanding was always that aside from vanity castles like Craigdarroch (https://thecastle.ca) there aren't castles in North America because they're only practical in a pre-cannon world

Castles became star forts, with stone/brick augmented with massive amount of earth. These were relatively effective against artillery into the 20th century.

Castles are practical against cannons but only if built with thicker walls than typical.
