Scone Palace is family home of the Earls of Mansfield. As can be seen in the Google street view cars are left in the ample car park. Admission can be to the grounds only or grounds and the Palace. I would recommend a visit to the Palace itself as the interiors and contents are very impressive.
Rotate the above view 180 degrees to see the parking area.
Rotate the view above to see Scone Palace. Moot Hill in Scone was the Ancient Crowning Place of the Scottish Kings. They were crowned on an ancient mound which now has a small chapel built on it.
