How filthy were Medieval Towns?
Well, they were certainly smelly - an inevitability when you realise all major transport into and, often, within, the Town is by animal ... horse, mule or donkey ... coupled with the reality that most households of any size kept animals (cows and goats for milk, chickens for eggs etc.) ... then there was the matter if industry, many of the processes used with raw materials used smelly materials or caused smells, so much so they were often legally forced to reside in specified areas within or, sometimes, outside, of the Town walls.
So we can agree they smelled.
But how dirty were they?
Not necessarily as much as is usually implied by the sources. See, most popular sources provide shock value snippets that, at first glance, make medieval towns out to be little better than a combination of an untreated dung heap and random garbage dump.
The problem is those snippets are chosen for effect ... often without any underlying research to support the implied conclusion of rampant filth ... or are simply repeated as 'everyone knows' factoids.
Yes, there were ordinances that, for example, Butchers weren't supposed to leave entrails and offcuts laying outside their shops or simply throw them into the road ... so, sure, it must have happened ... but how often?
Modern states have laws that require cleanliness in food preparation facilities ... but, occasionally, some of them are closed down or fined for breaches, probably only a fraction of a percent of the actual number. And check out the alley behind your local restaurant strip, especially in the crowded inner city, and breathe in the ... reek ... of rotting food ... which, yes, will be picked up and removed in a timely fashion, but still ...
So, what was the actual situation in Medieval Towns? For a start, each Ward had a civic official who was in charge of ensuring the streets were, if not pristine, at least as clean as they could be and that refuse and waste didn't block passage or make it too unpleasant ... and he was in charge of 'encouraging' householders and business owners to keep their personal patch clean as well as being in charge of what we can loosely call 'Garbos' in the Australian vernacular (aka 'Sanitation Workers'). In London they were called Rakers and their job was to physically remove refuse and waste from the streets.
No, there were nowhere near enough. But an effort was made ... and most householders did co-operate. As did most business owners ... in fact, in many towns there were specially designated areas outside (and away from!) the walls for use by each Trade as a dumping ground for their refuse.
Many towns had something like a garbage collection service - municipally owned (or contracted) Carts would come around semi-regularly and collect refuse ... unfortunately, details are sketchy and it is not clear how frequently these services were. Still, again, an effort was being made.
Then there were the municipal Lavatories ... which were placed at strategic points around the city and kept clean (and regularly emptied) by the authorities. Larger households had their own and paid for them to be emptied by specialist carters on a regular basis ... and tenants in dwellings (or rooms) too small to have their own used chamber pots or the nearest municipal facility (and they could empty their Chamber Pots there as well).
Sure, there were ordinances about people throwing the contents of their full chamber pots out the window into the street and, possibly, onto the passers-by below ... so it obviously happened sometimes. But probably not as frequently as is implied given the efforts the authorities went to ensure that at least some basic sanitary measures were in operation.
The other thing to be beware of is anachronism - many of the stories of civic filth, and usually the worst and grossest ones, actually postdate the medieval period and by a lot!
Giant dungheaps several storeys high, streets so swimming in ... crap ... that ladies often wore wooden pattens (raised oversoles) on their shoes so they could keep the hems of their dresses (and the soles of their shoes!) above the filth. Street urchins with brooms offering to sweep the piles of ... crap ... out of the way of the well-to-do crossing a street ... that's all 18th and 19th century stuff.
Interestingly, I came across a mention of a report of a major late 19th century Urban Planning conference (an international one) in London where the planners were wrestling with, amongst other things, the problem of horse byproducts (liquid and solid). They were almost literally tearing their collective hair out ... even with the new, expanded, sewer systems they were putting in they were recognising they were fast approaching the absolute physical limit of how much horse ... crap ... they could deal with. And further recognising that the amount of animals needed to move goods and people around massive conurbations such as London (and other places) was accellerating ...
That sort of problem was a very late development for mega-cities with a million or more people ... Medieval London, for example, probably had between 20,000 and 100,000 during the 11th-14th centuries ... and a fraction of the problem.
(Oh, the solution to the Urban Planning nightmare? One they didn't see coming ... the Motor Vehicle. Took all the horse crap off the roads ... but, of course, brought its own brand of pollution with it).
So, medieval towns won't be pristine ... and they won't be smell free ... but you won't be swimming in crap and piss or feeling vomitous from the extreme stench ...
