Definition
An enclosure; specifically, the enclosed precinct or circuit surrounding a monastery or similar religious institution. The term appears in old English legal records to describe the physical and juridical boundary demarcating the monastic close — the enclosed ground within which the community and its associated buildings sat. As both a physical and a legal concept, the inclaustrum defined the spatial limits of the religious house's protected precincts, carrying implications for jurisdiction, sanctuary, and property rights over the enclosed ground.
Why It Matters in Research
INCLAUSTRUM is an archaic Latin term confined almost entirely to medieval English ecclesiastical and monastic records. Researchers are most likely to encounter it in:
— Pre-Reformation property records involving monastic estates, particularly grants, confirmations, and conveyances touching the lands immediately surrounding an abbey or priory.
— Ecclesiastical court records and visitation documents, where the physical boundaries of the monastic precinct had jurisdictional significance.
— Post-Dissolution records (after 1536–1541) in which former monastic enclosures were converted to secular ownership and the old descriptive terminology was carried over into Crown grants and subsequent conveyances.
The primary trap for researchers is treating the term as purely architectural when it carried genuine legal weight. The inclaustrum was not merely a description of walls or fences; it defined the zone within which the monastery exercised its peculiar jurisdiction and within which the rules of sanctuary, trespass, and internal governance applied. Confusing it with the broader monastic demesne or the outer granges of an estate will distort the legal picture.
Because the term virtually disappears after the Dissolution, it does not appear in later English common law dictionaries or in equity practice. Researchers tracing the same physical ground in post-Reformation conveyances will find the concept absorbed into ordinary enclosure and real property vocabulary — look for "close," "precinct," "site of the late monastery," or "circuit" in the successor documents.
Historical Dictionary Support
Burrill's Law Dictionary (the sole shelf source carrying this term) defines it concisely as "an enclosure; the enclosure or circuit of a monastery," citing Spelman's Glossarium Archaiologicum — the standard authority for medieval Latin legal terms in the English tradition. Burrill's entry is accurate but minimal, offering no elaboration on the legal consequences that attached to the inclaustrum as a jurisdictional boundary.
Spelman himself, in the Glossarium, treats the inclaustrum in the context of the claustrum — the cloister proper — distinguishing the interior monastic buildings from the encircling precinct as a whole. This distinction is worth preserving in research: the claustrum (cloister) referred to the internal garth and surrounding walkways, while the inclaustrum designated the entire enclosed circuit of the house. The prefix in- here functions expansively rather than negatively, denoting the whole of what lies within the enclosing boundary.
No entry for INCLAUSTRUM appears in Cowell's Interpreter, Jacob's Law Dictionary, Bouvier's Law Dictionary, or Black's Law Dictionary in any edition, which reflects the term's narrow temporal and subject-matter range. Its absence from the common law dictionaries is itself informative: by the time English legal lexicography was systematized in the seventeenth and eighteenth centuries, the term had become a historical curiosity rather than a live legal concept.
Jurisdictional Note
Effectively limited to English law, and within English law to the medieval and early modern periods. No parallel usage appears in Scots or Irish ecclesiastical records under this specific term, though functionally equivalent concepts existed in those jurisdictions under different Latin formulations.
