Wouldn’t the more sensible thing be to build it on the road leading to the nation? I don’t know, this is just my input on it of course and I am willing to be wrong.

Oh god! How will the ignorant and helpless players ever find their way around a simple fort!? Surely we couldn’t just let them rely on common sense and co-ordinates! And build another road!? PAH!

It depends on the intent of Renatus.  If they want to protect specifically their own road to their city, then yes, although if their enemies are in the north, and they want to inhibit the northern nation/s, forming such a roadblock would be a good tactic for doing so, especially when you consider to get around that roadblock when approaching from the north you have to either swim across that small river next to the roadblock, or go right around Renatus so that you’re approaching from the south.  I believe this fort is a good tactic of warfare, without needing to send a group of goons to attack your target.
