Here’s a summary of the construction and history of San Silvestru Windmill in Mosta, Malta:
📍 Location
35.903956, 14.423483Identification & location
Common names: Ta’ Triq San Silvestru Windmill, sometimes simply “San Silvestru windmill.”
Address / location: recorded on Triq San Silvestru (crossing Triq it-Tori / near the chapel of San Silvestru) in Mosta. Map/photo metadata places it in the Ta’ Mellu / Mitħna area of Mosta.
Short summary
A small tower-type grain windmill from the British period (c.1800), built to serve Mosta’s agricultural hinterland; it lost its sails and has been adapted/partially demolished in later years (the base survives and has been incorporated into private property), and the site is scheduled/protected under heritage controls so nearby development is constrained.
History & chronology
Construction / date: commonly dated c.1800 (start of the 19th century / British period) in specialist windmill registers and local guides; it was built as one of Mosta’s village mills serving local farmers.
19th–20th centuries — use: used as a grain mill (wheat/barley to flour). Like most Maltese/Gozo mills it remained useful until motorised milling reduced demand for small windmills. Published notes record regional mills remaining in use into the early 1900s; for this specific mill sources are consistent that it stopped regular milling with the general early-20th-century decline.
Later changes / fate: secondary compiled lists and local notes indicate the tower was demolished at some point and the base was converted to residential use (i.e., only the base survives in adapted form). That demolition/conversion pattern matches many Maltese urban/countryside mills. Some popular-photography pages still point out the nearby “Il-Mithna l-Gdida” (the New Mill) and the cluster of Mosta mills, so check photos carefully before assuming which mill is visible.
Architecture & construction details
Type: Tower (round) windmill — the classic Maltese “tower + base” plan (cylindrical stone tower on a stone base containing storage and living rooms).
Materials & method: local globigerina limestone masonry with lime mortar; timber sail-arms and simple wooden gearing originally. This is the standard material palette for Maltese mills of the period.
Mechanics (historical): would have had a horizontal windshaft with wooden arms (4–6 sweeps), a brake wheel and vertical shaft driving a runner stone over a bedstone; no functioning mill machinery survives in place today for most of Mosta’s small mills.
Current status, protection & planning context
Heritage & protection: the San Silvestru / Mitħna area is part of Mosta’s historic mill cluster; conservation buffers around mills often apply. Recent planning coverage has highlighted that the buffer around the Grade-1 scheduled San Silvestru windmill constrains nearby development proposals — for example a 2021 MaltaToday article reported a proposed residential block that would have been only ~22 m from the windmill’s buffer and triggered heritage discussion. This confirms statutory protection/recognition in planning practice.
Physical condition / access: public sources describe the tower as removed / reduced and the base adapted (private use). There is no open museum function for this mill; any surviving base fabric is on private property or within an urban block. If you need to visit, treat it as private property unless you find a public access notice.
