A striker, Holst started his career at Danish lower division teams Thurø and Svendborg before moving to Lyngby Boldklub in 2003.
In 1907 he designed a house for the Danish composer Thorvald Aagaard in Ryslinge on the island of Funen and subsequently another house in Svendborg.
One of the most controversial times for the friary was in 1500 when Queen Christina, who was at that point in direct control of Svendborg, gave the whole of Bysen Street (Bysenstræde) to the Franciscans to use as accommodation for the town's poor and sick in their care.
