Ditherington Flax Mill Maltings

Visitor Centre (converted Stables)

Date

26 August 2017

Location

Ditherington, Shrewsbury
SJ 49855 13826; 52.71974°N, 2.74382°W

Information

Ditherington Flax Mill Maltings was previously featured here in GeoTopoi in December 2011. Since then there have various changes at the site, the most significant being the opening in November 2015 in the converted offices and stables of a Visitor Centre. The opening of the centre is the first phase of a restoration project undertaken by a partnership between Historic England, Friends of Flaxmill Maltings and Shropshire Council. The second phase, which will result in a mixed-use redevelopment of the historic buildings, is proceeding thanks to the subvention of the Heritage Lottery Fund.

Other changes include the demolition of various later structures on the site, such as the massive concrete silos built in the 1950s and 60s (North Silo and South Silo). Public access is currently limited to the Visitor Centre and a small area to the rear of the mill buildings.

Hydro Ogwen Scheme

Weir above Ogwen Bank Falls

Date

25 June 2017

Location

Ogwen Bank, Bethesda
SH 62608 65410; 53.16801°N, 4.05676°W

Information

Hydro Ogwen is a community hydro-electric generation scheme on the Afon Ogwen owned and operated by Ynni Ogwen Cyf (Ogwen Energy Ltd), a company established in 2015 to complete the development of the project and to manage it thereafter. The venture was financed by £450k raised via a community share offer and profits are to be distributed for the benefit of the local community.

Family-run contractors Gwyn Roberts Construction, based near Bala, carried out the building work, which started in July 2016 and was mostly completed by March 2017. The 100 kW generator, whose estimated annual output will be 500 MWh, is driven by a turbine fed via a 900 mm diameter pipe buried under the Lon Las Ogwen path with water abstracted from the intake weir, approximately 300 m upstream, just above the waterfalls at Ogwen Bank.
