The slate quay at Tyddyn Isa near Maentwrog
Before the opening of the Ffestiniog Railway and the development of Porthmadog as a port, slate was exported from several quays on the Afon Dwyryd near Maentwrog. The slate reached here on horse drawn carts from the Blaenau Ffestiniog quarries. It was then loaded into small sailing boats and taken out to larger vessels anchored at the mouth of the Glaslyn. The full story of this interesting period may be read in the book "Sails on the Dwyryd" by M.J.T. Lewis, ISBN 0 9512373 3 0. To give some idea of the importance of this trade, it is estimated that over 420,000 tons of slates were exported from these quays over their lifetime. The Afon Dwyryd can no longer be reached by sailing vessels due to the construction of the Aberystwyth and Welsh Coast Railway bridge, near the mouth of the river, in 1867.
The
best preserved of these quays is Tyddyn Isa which can be reached by a public
footpath from the A487 between Maentwrog and Penrhyndeudraeth. The
whole structure is 211m long, it was constructed in 1824 and last
used in the 1860s. There are two well preserved buildings on the
site, the larger one being an explosives store and the smaller, probably,
an office. It is a fitting tribute to the builders of Tyddyn Isa
that the quay could still be used again today.

upright slate slabs would have been used to hold the sailing boats fast
during loading.
The
stone used in construction was quarried from the rockface behind the quay.
