On 21st September, 2002 stonemason Ray Collins commenced work on a commemorative garden in recognition of the Australian emigrants who arrived on the First Fleet at Botany Bay in 1788. 

Of the emigrants who were actually convicts, six were Welsh, four men and two women and by 1852, the number of transportees who had been tried in Wales had risen to approximately 1,800, of whom, 300 were women.  These included  Lewis Lewis  for his part in the Merthyr Riots of 1831 and the Chartist leaders John Frost, Zephaniah Williams and William Jones for their organising of the Newport Rising of 1839.  

In September 1938, flooding caused the Dolaucothi Gold Mine in Carmarthenshire to finally close.

It is thought that the mine at Dolaucothi was first opened in the late Bronze age, perhaps as early as 600 BC.  However, serious excavation commenced in approximately 75 AD,  during the Roman rule of Britain.  The Romans used slaves for the hard manual labour of extracting the gold deposits, which were destined for the Imperial Mint in Lyon.

Following the Romans' departure from Britain, it wasn't until the 17th or 18th centuries that mining recommenced at the site on a small scale but it was in the 19th that there was expansion beyond the original open cast.  A large amount of ore was extracted during the 1930s, but after 1938 the mine was no longer used for commercial enterprise and it is now owned by the National Trust.   

On 21st September 1987, there was a reported sighting of the Afanc of Llyn Llangors (Llangorse Lake) 

The Afanc is a lake monster from the mythology of Wales, described as taking the form of a giant beaver or large crocodile, which devoured anyone or anything that entered its waters.

The earliest known literary reference to the Afanc is in a poem by the 15th century Welsh poet, Lewys Glyn Cothi.  One legend tells of the wild thrashings of the afanc causing flooding and another tells of a maiden taming the Afanc and letting it sleep in her lap, whilst other villagers attempt to capture it.  However, the Afanc awakes and crushes the maiden.  Later legends have King Arthur  slaying the Afanc in Llyn Barfog in Gwynedd.  Nearby is a rock with a hoof print mark in it, which was supposedly made when Arthur's horse, Llamrai, dragged the Afanc from the lake.   Iolo Morgannwg then popularised a version in which two long-horned oxen dragged the Afanc from the lake, to be killed.  

On 21st September 1949, the Prince Llewelyn Hotel in Beddgelert, Gwynedd was hit by a meteorite.  It is only the second ever known to hit Wales, the other falling in 1931, at Pontllyfni, near Caernarfon.

The meteorite was preceded by a brilliant light and a series of dull explosions, which ended with a buzzing sound and the sound of roof slates shattering.  The following morning a dark-coloured stone the size of a cricket ball was found on the floor of the attic.   

The first comprehensive school in England and Wales opened on 21st September 1949 as Holyhead County School.
