More than a century after being donated its first ever place - five acres of cliff top at Barmouth in Gwynedd - National Trust is turning 125.

Dinas Oleu was handed to the charity on 29 March 1895 by Fanny Talbot.

Mrs Talbot was a philanthropist, land owner and friend of two of the charity's founders - Octavia Hill and Canon Hardwicke Rawnsley.

Mrs Talbot was born in 1824 in Bridgwater, Somerset, and moved to Ty'n-y-Ffynon, on the slopes of Dinas Oleu, following her husband's death and devoted herself to local philanthropic work.

Since those early days the charity has grown to be Europe's largest conservation charity with almost six million members.

It preserves more than 250,000 hectares of countryside, 780 miles (1,255 km) of coastline and hundreds of special places across Wales, England and Northern Ireland.

In Wales it owns 157 miles (253 km) of coastline, more than 46,000 hectares of land as well as castles, gardens and mansions.

To mark the milestone, the charity's director general Hilary McGrady announced plans for it to become carbon net zero by 2030 and plant 20 million trees over ten years.

Powis Castle was built in the mid-13th Century by Welsh prince Gruffudd ap Gwenwynwyn.

This was in contrast to the other castles of north Wales, such as Caernarfon, Harlech and Conwy, which were built by the English to consolidate Edward I's conquest of Wales.

The castle was transformed into a grand residence in the 1530s by Edward Grey, Lord of Powis.

In 1578 it was leased to Sir Edward Herbert who bought the castle in 1587.

It remained in the Herbert family until 1952, when it was bequeathed to the National Trust, with Lord Powis retaining ownership of the surrounding estate and parkland.
