The numbers are:

1 Hill Fort
2 Fortress
3 Fortified City
4 Tel City
5 Swamp City
6 Peg Castle
7 Motte and Bailey
8 Citadel
9 Mountain Citadel
10 Fortress
11 Swamp Fort
12 Kelp Fortress
13 Kelp Citadel
14 Dark Citadel
15 Cave City
16 Cave Castle
17 Wizard's Tower
18 Dark Citadel
19 Living Castle
20 River Fortress
21 Jervellan Wall
22 Archaic Fortress
23 Firbolg Fortress
24 Crystal Citadel
25 Obsidian Citadel
26 Dead City
27 Ermorian Castle
28 Ermorian Citadel

Supposedly Fort Numbers go from 1-20, but 21 through 28 have 1:1 correspondance with these other fortresses which totally exist. I don't know what the deal there is.
