In medieval Europe, cleaning cesspits—also called cesspits or gong pits—was not a minor or improvised matter. There was a specialized and regulated profession: the gong farmers, workers who, with nightlife and effort, maintained the hygiene of castles, mansions and urban centers.
Who were the gong farmers?
The gong farmers were specialized workers in charge of emptying and cleaning the pits of human excrement and waste. It was not a temporary trade or unrelated workers: it was a technical job with its own practices and standards, often inherited from generation to generation within families that were specifically dedicated to it.
Origin of the name and meaning
The term combines two Old English elements: gong, which was used to refer to the excrement deposit, and farmer, which here does not mean a farmer but someone who “manages” or “harvests” a resource. That is, the gong farmer was the one who collected and managed human waste from health facilities.
Main functions
- Empty and clean blind wells and primitive septic tanks.
- Extract and transport waste outside the walls or to disposal points.
- Repair or maintain latrine structures and drainage pipes.
- Record incidents and comply with municipal regulations on schedules and discharges.
Working conditions and tools
It was night work by ordinance in many cities (for example, London since the 11th century) to avoid odors and nuisances. They worked in narrow, deep and poorly ventilated spaces, with a series of risks that we understand better today thanks to archaeological finds and municipal records.
- Tools: reinforced wooden shovels, waterproofed buckets and baskets (often with tar), pulleys and containers for extracting the material.
- Times: strictly at night in urban areas; clandestine daytime work was sanctioned.
- Practices: use of ropes and pulleys to lift loads; sometimes transported outside the wall or sold as fertilizer in rural areas.
Risks: gases, collapses and diseases
The wells accumulated toxic gases—methane and hydrogen sulfide among them—which caused asphyxiation and documented deaths. Other frequent dangers were wall collapses, infections from direct contact with contaminated material and physical wear and tear due to high-effort work in adverse conditions.
- Asphyxia due to gas accumulation.
- Accidents due to collapse or lack of oxygen in deep pits.
- Exposure to pathogens and chronic skin or respiratory problems.
Social situation and economy of the trade
Despite the risk and social disdain, some gong farmers received significant remuneration; There are records indicating that they could earn between 6 and 8 times the salary of a peasant for a night's work, which provided them with relatively high resources. However, this economic prosperity coexisted with strong social marginalization: they lived on the urban margins, were prohibited from accessing markets or public places during daylight hours, and their trade was stigmatized.
Regulation and control
Urban authorities imposed ordinances to minimize health risks and inconveniences. Among the usual measurements:
- Prohibition of cleaning or dumping waste during the day.
- Fines for spills or non-compliance with transportation routes.
- Municipal licenses or concessions to act within walls or noble properties.
Archaeological value and testimonies
The blind wells are real time capsules. When emptying them, the gong farmers exposed strata with food remains, seeds, bones, textiles and lost objects such as coins or ceramic fragments. These materials offer archaeologists and anthropologists a direct window into the diet, habits and economy of the medieval population.
Relevant historical examples
In military contexts, knowledge of passages and ducts associated with latrines was used in sieges. A case noted in medieval sources is that of Château Gaillard (1204), where underground passages related to maintenance and sanitation played a role in the fall of a fortress. Additionally, municipal minutes from cities such as Paris and York document fines and regulations on the activity.
| Appearance | Features |
|---|---|
| Schedule | Mainly nocturnal due to municipal ordinances. |
| Tools | Shovels, buckets, waterproofed baskets, pulleys. |
| Risks | Toxic gases (methane, H2S), landslides, infections. |
| Remuneration | May be high compared to agricultural wages; high-risk, high-demand work. |
| Archaeological value | High: well-preserved organic materials and artifacts. |

Legacy and reflection
The gong farmers illustrate how medieval urban life depended on marginal but essential professions. Their work enabled the habitation of densely populated spaces before modern sewage systems and left a material record that today fuels historical research. Although socially repudiated, their role was decisive for public health and the continuity of daily life in castles and medieval cities.
