A polis is also a place made up of physical spaces. Physically, the Greeks understood a polis to be made up of city itself, which might just be called the polis but also the astu (ἄστυ, “town”), and the hinterland or countryside, generally called the chora (χώρα). The fact that the word polis can mean both the city and the (city+chora=state) should already tell you something about the hierarchy envisaged here: the city is the lord of the chora. Now in the smallest of poleis that might make a lot of sense because nearly everyone would live in the town anyway: in a polis of, say, 150km², no point might be more than 8 or 9 kilometers from the city center even if it is somewhat irregularly shaped. A farmer could thus live in the city and walk out – about an hour or two, a human can walk 6-7km per hour – each morning.

But in a larger polis – and remember, a lot of Greeks lived in larger poleis even though they were few, because they were large – the chora was going to be large enough to have nucleated settlements like villages in it; for very large poleis it might have whole small towns (like Eleusis or Thoricus/Laurion in Attica, the territory of Athens) as part of the chora. But we usually do not see a sort of nested heirarchy of sites in larger poleis; instead there is the astu and then the chora, the latter absorbing into its meaning any small towns, villages (the term here is usually kome), isolated homesteads or other settlements. The polis in the sense of the core city at the center of the community was not a settlement first-among-equals but qualitatively different from every other settlement in the polis – an ideal neatly expressed in that the name of the city served as synecdoche for the entire community (imagine if it was normal to refer to all Canadians as “Ottawans” regardless of if they lived in Ottawa and indeed to usually do so and to only say “Canada” when it was very clear you meant the full extent of its land area).

That is not to say that the astu and chora were undivided. Many poleis broke up their territory into neighborhood units, called demes (δημοι) or komai (κῶμαι, the plural of kome used already) for voting or organizational purposes and we know in Athens at least these demes had some local governing functions, organizing local festivals and sometimes even local legal functions, but never its own council or council hall (that is, no boule or bouleuterion; we’ll get to these next time), nor its own mint, nor the ability to make or unmake citizen status.

There are also some physical places in the town center itself we should talk about. Most poleis were walled (Sparta was unusual in this respect not being so), with the city core enclosed in a defensive circuit that clearly delineated the difference between the astu and the chora; smaller settlements on the chora were almost never walled. But then most poleis has a second fortified zone in the city, an acropolis (ἀκρόπολις, literally “high city”), an elevated citadel within the city. The acropolis often had its own walls, or (as implied by the name) was on some forbidding height within the city or frequently both. This developed in one of two ways: in many cases settlement began on some defensible hill and then as the city grew it spilled out into the lowlands around it; in other cases villages coalesced together and these poleis might not have an acropolis, but they often did anyway. The acropolis of a polis generally wasn’t further built on, but rather its space was reserved for temples and sometimes other public buildings (though “oops [almost] all temples” acropoleis aren’t rare; temples were the most important buildings to protect so they go in the most protected place!).

While the street structure of poleis was generally organic (and thus disorganized), almost every polis also had an agora (ἀγορά), a open central square which seems to have served first as a meeting or assembly place, but also quickly became a central market. In most poleis, the agora would remain the site for the assembly (ekklesia, ἐκκλησία, literally “meeting” or “assembly”), a gathering-and-voting-body of all citizens (of a certain status in some systems); in very large poleis (especially democratic ones) a special place for the assembly might exist outside the agora to allow enough space. In Athens this was the Pnyx but in other large poleis it might be called a ekklesiasterion. The agora would almost always have a council house called a bouleuterion where a select council, the boule (βουλή) would meet; we’ll talk about these next time but it is worth noting that in most poleis it was the boule, not the ekklesia that was the core institution that defined polis government. In addition the agora would also house in every polis a prytaneion, a building for the leading magistrates which always had a dining room where important guests and citizens (most notably citizens who were Olympic victors) could be dined at state expense. Dedicated court buildings might also be on the agora, but these are rarer; in smaller poleis often other state buildings were used to house court proceedings. Also, there are almost always temples in the agora as well; please note the agora is never on the acropolis, but almost always located at the foot of the hill on which the acropolis sits, as in Athens.

And this is a good point to reiterate how these are general rules, especially in terms of names. Every polis is a little different, but only a little. So the Athenian ekklesiaterion was normally on the Pnyx (and sometimes in the Theater of Dionysus, an expedient used in other poleis too since theaters made good assembly halls), the Spartan boule is the gerousia, the acropolis of Thebes was the Cadmeia and so on. Every polis is a little different, but the basic forms are recognizable in each, even in relatively strange poleis like Sparta or Athens. But it really is striking that self-governing Greek settlements from Emporiae (Today, Empúries, Spain) to Massalia (Marseille, France) to Cyrene (in modern Libya) to Panticapaeum (in Crimea, which is part of Ukraine) tend to feature identifiably similar public buildings mirroring their generally similar governing forms.
