A port city can be any city that has seaward access and exists within a
province (4) or greater. In my mind all that would be needed to turn such
a village or town into a port would be the construction of docks and a
sheltered harbor. This is, of course, a much bigger undertaking that
building a wooden town hall mind you. The docks must be big enough and
strong enough to handle Anuirean galleons, some of the largest boats
afloat.

I would say that you could use the rules for creating a castle, perhaps,
and call the level of the port equal to the level of the province, thus
indicating the gold bar expenditures. (Check Fortify in the rulebook).

All this assumes you are building the port to begin with. If you are
building a realm scratchbuilt, I see no reason why any city in such a
position would NOT be a port.

And, if I may, it is a pleasure to see that gaming has stepped beyond the
guys. Welcome to the list! :)


Good Gaming!
