Look
at any old building and what do you see ???. Blue Bangor Slate
Roofs. Schools, Churches, Courthouses, Great Houses, they all have
one thing in common - Blue Bangor Slates. It is no accident that
such slates were used and are still being used.
Slates
and Ports
Quarry
slates invariably took their names from the Port of shipment rather
than the producing quarry, examples such as Irish Killaloes, (there
is no slate quarry in Killaloe) from the Portroe Quarries,
Blue Bangor from the Penrhyn Quarry at Bethesda shipped through
the port of Bangor in North Wales, Slates from Llanberris
valley shipped from Port Dinorwig including Dinorwic and
Vivian Quarries, Slates from the Nantlle Valley shipped from Port
Caernarfon including Dorothea and Pen-yr-Orsedd Quarries, Slates
from Blenau Ffestiniog Valley shipped from the port of Porthmadog
including such quarries as Gloddfa Ganol, Oakeley, Votty, Cwt y
Bugail and Llechwedd.
