Details

The scheduling includes a mid-19th century lighthouse-builders' operational
base on the island of Rosevear in the Western Rocks of the Isles of Scilly;
the base served the builders of the Bishop Rock Lighthouse during its initial
and abortive construction attempt from 1847-1850 and during its successful
construction from 1851-1858.
The structures of the base extend across the north east and east of this small
rocky island, occupying the only area sufficiently level and high enough to
escape the reach of the highest tides. At least four main elements survive.
Two buildings, a workers' lodging and mess building and a workshop building,
are grouped in the north west of the overall structural complex; a smithing
hearth is located between them; the fourth element, a slab-built platform, is
situated to their east by the island's east coast. Traces of a third building
are also visible further south on the east coast.
The operational base was established on Rosevear following the decision by
Trinity House in April 1847 to erect a lighthouse on the Bishop Rock, 3.2km
WNW of Rosevear, marking the notoriously dangerous reefs and rocks at the
south west edge of the Scilly archipelago. Rosevear was chosen for the base as
it is the nearest island with any substantial area of flattish dry land; the
Bishop Rock is a short distance by boat and clearly visible from the island,
enabling work to proceed whenever conditions were seen to be suitable.
Under the direction of Nicholas Douglass and his son James, the lighthouse was
built to an initial design of an open framework of cast iron columns and
wrought iron stays, supporting a lantern and living accommodation. The
structure was almost finished by the end of the 1849 season but was completely
destroyed in a storm on 5 February 1850. Following a rapid and radical
reassessment, the proposed design was changed to a granite tower and work
began, again under the direction of the Douglasses, to prepare the rock for
the tower in summer 1851; the stonework was completed in 1857 and its light
was first displayed in 1858. Rosevear was again chosen as the base for the
workforce, though their role was limited to assembling the structure. The
stone used for the tower came from the mainland quarries at Carnsew and
Lamorna; it was shipped to Scilly for final dressing to shape on St Mary's,
and finally transported by tender and barge directly to the Bishop Rock.
Records illustrate the living conditions of the workforce on Rosevear, noting
that to supplement provisions brought from the main islands, some vegetables
were grown in rock crevices, fish were caught and sea-bird eggs varied the
diet. The base was frequently cut off by bad weather and on occasion the
workers were reduced to eating limpets. Despite the hardships, on one evening
the workforce gave a `grand ball', clearing and brightly lighting all of the
buildings, which had been decorated with bunting; invitations went out to the
rest of Scilly and the visitors danced into the early hours of the following
morning, returning by boat in the moonlight.

Reasons for Scheduling

The Isles of Scilly, the westernmost of the granite masses of south west
England, contain a remarkable abundance and variety of archaeological remains
from over 4000 years of human activity. The remote physical setting of the
islands, over 40km beyond the mainland in the approaches to the English
Channel, has lent a distinctive character to those remains, producing many
unusual features important for our broader understanding of the social
development of early communities.
Throughout the human occupation there has been a gradual submergence of the
islands' land area, providing a stimulus to change in the environment and its
exploitation. This process has produced evidence for responses to such change
against an independent time-scale, promoting integrated studies of
archaeological, environmental and linguistic aspects of the islands'
settlement.
The islands' archaeological remains demonstrate clearly the gradually
expanding size and range of contacts of their communities. By the post-
medieval period (from AD 1540), the islands occupied a nationally strategic
location, resulting in an important concentration of defensive works
reflecting the development of fortification methods and technology from the
mid 16th to the 20th centuries. An important and unusual range of post-
medieval monuments also reflects the islands' position as a formidable hazard
for the nation's shipping in the western approaches.
The exceptional preservation of the archaeological remains on the islands has
long been recognised, producing an unusually full and detailed body of
documentation, including several recent surveys.

The lighthouse-builders' operational base on Rosevear provides a rare example
of a mid-19th century workshop and workers' lodging complex which survives
substantially intact and unaffected by later modification and adaptations. The
construction of the Bishop Rock lighthouse, for which this operational base
played an essential role, marks an important stage in the developing capacity
of Trinity House to tackle the more difficult and serious navigational hazards
which faced the nation's shipping. The surviving remains on Rosevear,
complemented by the records associated with them, illustrate well the
ingenuity, spirit and the hardships involved in overcoming the enormous
practical difficulties presented by the need to build a lighthouse on such an
exposed, remote and restricted location using mid-19th century technology.
