An
Iron Age hillfort
Prideaux Castle lies a mile to the north west of the town in the parish of
Luxulyan. The Biscovey Stone is the shaft of an ancient
Celtic cross. It was inscribed, but the text is no longer readable. There are several theories about the stone; one says it dates from around 600 AD to show the
Saxon advance into the county, another puts the date at around 900 AD. The head is thought to have been removed during the
Reformation. The stone served as a gate post near the St Blazey turnpike gate. In 1896 it was moved to St Mary's Church, Biscovey. The church was built between 1440 and 1445 and is dedicated to Saint Blaise. It replaces an earlier church mentioned in 1294. The parish was administered by
Tywardreath Priory until the Reformation. Until the 16th century the valley below St Blazey was an estuary of the
River Par and St Blazey was the
lowest crossing point on the river.
Tin mining up river caused the estuary to silt up and it had become marsh land by the early 19th century. The
Par Canal was built by
Joseph Treffry between 1829 and 1835; it forms part of the boundary with the parish of
Tywardreath and Par. The town was once dominated by the local mining industries and their associated transport infrastructure. Historically copper and
tin were mined in and around the parish, whilst more recently
china clay has been the principal commodity mined. "The Par & St Blazey Consols" or "South Prideaux Wood" was a small tin mine just north of the town and
Par Consols Mine lies to the south west. The more extensive
Fowey Consols mine lies to the east near
Tywardreath. The port of
Par Harbour, which lies within the parish, was developed to ease the transport of these minerals, and initially connected to the mines by the
Par Canal. Whilst the port of Par is within the parish, the village of
Par is actually just across the
River Par, and hence lies in the civil parish of Tywardreath. The Par Canal was soon replaced by the
Cornwall Minerals Railway, which had a depot and station in the town, and still exists as part of the
Atlantic Coast Line. Whilst
St Blazey depot is still in use,
St Blazey station closed to passengers in 1925, and the town is now served by
Par station on the
Cornish Main Line in Par village. ==Tourism==
