Yes, so-called ideal cities. One planned them directly completely in an ideal form.
But this ideal form has rarely been preserved as perfectly as in Palmanova.
The military architect Giulio Savorgnano designed it as a Venetian military station on the eastern border as a protection against the Ottoman Empire, and that's why it's actually originally a fortress.
I lived in Italy for 15 years and I don't know it, I really wonder why.
Probably because it's in Friuli, a region I've rarely been to.
Palmanova has almost 5500 inhabitants and was laid out as a planned town at the end of the 16th century.
It is star-shaped and this layout has been perfectly preserved. The city was planned and implemented with radial road network.
The wide streets were intended to serve the soldiers to get out of the center, where the parade ground is located and ….
...to get to the city walls, which were, after all, the defenses.
On the very outside lived the mercenaries, a ring further inside the line soldiers and in the very center the officers.
