The Barton of Merthen has belonged to the Vyvyans of Trelowarren for three hundred years.

 It occupies a promontory  that runs out into a long tail-like point, known as the Groyne, between the two principal arms of the Helford River. From the Barton House, and still more from the ancient earthworks 350 yards northwest of it, one obtains a view that commands the mouth of the Haven , and it is easy to understand why the Lords of Merthen have always had such extensive rights over the river. The meaning of the name Merthen is obscure. It has, however, nothing whatever to do with the place-name Merther implying a Chapel in honour of a martyr. The earliest spelling of the name, Meredin, suggests that it is called after a Din or fortress, and the  remarkable earthworks in the old Deer-park bear this out. These  earthworks (which have been described on p. 13) consist of two  rectangular enclosures, each of about one acre in area, which join each other at right angles. The site which they occupy is more commanding than the site of the farm house, and the line of a very  ancient ridgeway coming from Merthen Quay northwards passes through the western ditch of one of them. There are places called Merthen in St. Austell and Buryan. Both lie on the coast, the former on a long promontory not unlike  the Groyne, though the creek on one side of it has been filled up.The word Din , a fortress, latinized into Dunum, was used for a  chief’s residence or capital town. Moridunum (i.e. the sea-city) is  named in the Roman Itineraries as a port on the Roman road east of Exeter and is generally identified with Sidmouth. Merthen, the Meridin of the 12th century, may well have been another Moridunum, a fortress embraced by arms of the sea, which afforded a haven  protected from storms and hostile attack. Although Merthen has been a farm on the Trelowarren estate for  just three centuries, it has usually been occupied by well-to-do tenants  such as members of the Vyvyan family itself, the Tyackes etc. and it has preserved much of its former dignity. In the Middle Ages,


The road system of Constantine is not merely medieval, it is prehistoric. This is not intended to be a criticism of those who have charge of the roads but merely a statement of fact. There are no

roads in the parish worth mentioning that have been made in modern

times1.W e have seen that the principal roads leading northwards from the Helford River are ridgeways. The most westerly is still in use as the main road from Gweek to the Helston-Truro road (itself a ridgeway) at Buttres Gate. Beyond that it once continued by Stythians, Bissoe and

Baidu till it joined the principal ridgeway running along the watershed

from one end of Cornwall to the other. This road brought the tin

bearing region of Stythians into communication with the port of Gweek.

It enters Constantine parish at a place called Ponstreath or Ponstrays,

which is possibly a corruption of Penstrase, i.e., Street-end, the word strase or strad being used for a paved way, a relic of the Roman strata.A t Carloggas a fortification adjoined it. At Tolvan it was crossed by

the principal track leading across the parish, and the meeting place of the roads was doubtless suggested by the presence of the Tolvan


The second ridgeway from Gweek runs up to Carwythenack Chase, where an earthwork lies on its left hand3. Then it went straight up over the top of Brill hill, to Trevease, passing the stone cross at the ford, and so out to join the other ridgeway at Buttres Gate. This road is only used in its lower part, but it can be traced through the crofts on Brill hill by a double line of hedges.

Ancient Roads and Tracks 17

The third ancient ridgeway is that coming from the Quay at  Merthen Hole4, up through the woods, across the old deer park,  where it passes through the ditch of the earthworks, so out over the  Downs, across the fields to Brill. Then to Trewardreva and over the ford (Ret) which gave name to Retallack. So up the hill along past the  site of Maen Rock, skirting Treworvac, across the fields to the “ Dead lane” , where it proves its antiquity by being a part of the parish boundary, then into the Lestraines lane and out to the Turnpike from Helston to Truro at Rame. The “ Dead lane ” is a strip of this ridgeway which has not been used for over a century, and is so called because It is now a cul-de-sac. On either side of it is a tumulus, for barrows, like ancient roads, are found on ridges. It is remarkable that this lane, about three-quarters of a mile in length, is the only piece of road which forms part of the Constantine parish boundary. All the rest of the boundary is formed by creeks, streams, or, for a very small distance, by hedges. At Merthen Hole it is a typical pack-horse track cut out of the  rock. Its paving stones remain beneath the fields and make ploughing Impossible.The fourth main ridgeway is the present main road from Penryn, entering the parish near Bossawsack and continuing past High Cross down to the river at Calamansack. There are two principal tracks across the parish from east to west,  2nd as the lower has to traverse six deep valleys, it affords a good example of the precipitous nature of old roads.

This enters the parish from Mawnan at Tregarne Mill, passes the steep hill to Treworval , by what is now a rough lane, continues across the fields to Driff and Treviades, then down past Gwealllin to the creek-head at Polwheveral. This part bore the name Clodgy lane in 1649, a common name in Cornwall, derived, in all zbability, from Clud, a carriage, or perhaps from Clodding, meaning trenched ” or “ embanked5.” At the bottom stood two grist mills, d • Tucking or Fulling Mill. The bridge over the stream was built «57*> as appears from the contract between the parish and Roger Urd, a mason, of Tregoney, entered into the old Vestry Book6.
