All castles in Heroes 3.

I like Rampart. The tactics for it should be cautious; you can’t afford to lose a single unit, but by the end of the game, these concerns pay off, and these units, which are weak in health and don’t stand out in terms of hit points or damage, led by elves, tear apart even the highly praised Necropolis, binding vampires with dendroids, killing a bunch of skeletons with a horde of dwarves, and shooting a crowd of preserved elves at liches, finishing off the pitiful remnants. The only ones who can stand up to the elves with good gameplay are Fortress and Dungeon, which are also my favorite cities, and which very (very, very) effectively counter Rampart!
