Forts are super-strong defensive structures, and are also used to train a variety of units. Officers, spies, and all gunpowder infantry and siege units are trained from your forts.
Forts are available once Level 3 Military (Heraldry and code of honour) is researched, and depending on what you have researched, you can upgrade your forts to castles, and towers to keeps and bastions. Forts and Towers are upgraded to Castles and Keeps once Fortifications is researched, and can be upgraded again by Asian and Orthodox factions with Imperial Mandate at the Nobles' Court into Strongholds and Keeps, which are immensely strong.
Note, however, that despite being strong, Forts are vulnerable to siege weapons. The trebuchet, having the furthest reach in the entire game, can easily wreck anything with impunity regardless. Of lesser damage caused would be naval units, namely the Siege Galley; Carrack and Lanternas; a Castle with Military Engineering can match a Siege Galley in range; with Bombardment, Carracks are caught. Only a Stronghold with Bombardment can hope to hold off an attack by the Lanternas, and even so, several Lanternas will easily destroy a Stronghold through sheer determination and numbers.
