The hamlet known as Lastra (also spelled Lastre, Lasdref and Lasdred) is situated at Amlwch, Anglesey in north Wales. Circa 1803-1820 Reverend Edward Hughes, a major shareholder in the Parys Mountain copper mining development, owned property at Lastra; Griffith Roberts was his tenant. Later in the century, his son Rowland Roberts occupied property there. He was also involved, as a shareholder, in the Amlwch ships, Mary Hannah, John and William and the Mona and was the funds collector for the Bible Society, Gwredog division, c. 1840-1843.
Lastra farm is a highly commended hotel which caters from receptions, banquets and conferences.
