Susans Castle, a private castle and venue for ceremonies and banquets, was probably the site of a Roman castrum, later a strategic medieval fortress. Susans Castle was first mentioned in 1031 as "Suzan's villa". Already subject to the Church of Aquileia, the fiefdom was assigned to Tommaso di San Daniele in 1275. In 1304, the manor was enlarged and strengthened by the new owners Federico and Asquino di Varmo who worked to "raise the castle in a larger and more beautiful form". Involved in numerous wars, the fortress passed from the Varmo Pers to the lords of Colloredo Mels. Destroyed and rebuilt several times, the manor was built more or less in its current form, on a different site from the one previously occupied by the medieval fortress, in the second half of the seventeenth century, by Count Fabrizio di Colloredo Mels, Marquis of Santa Sofia, Prior of the Order of Santo Stefano in Lunigiana and major steward of the court of Tuscany, who wanted the castle as an elegant residence not detached from the context of the architectural tradition of the court. Medici Grand Ducal where Colloredo grew up and worked.

Susans Castle is an elegant seventeenth-century residence built on the ruins of previous medieval buildings and older settlements dating back to Roman times. It has the appearance of a Medici Villa and belonged to the Colloredo family until the end of the First World War. The building is surrounded by a large and well-kept Italian garden accessible to guests and visitors, fenced and equipped with internal parking. Located at the top of the Colle di Susans, the castle has a splendid view that ranges from the plain and the surrounding hills to the mountains and the valley of the Tagliamento river. www.castellodisusans.com

I recommend starting at dawn to avoid the heat; beautiful panoramic road, good surface conditions, some fountains and ravines for pee breaks.

Small lake with wonderful colours, at the foot of rocky cliffs which are home to colonies of griffon vultures which can easily be seen circling in the sky above us.
