Imagine an extraordinary and private manor, reminiscent of a grand castle overlooking the mighty Potomac River. Enormous, 14-feet tall carved mahogany doors grant entry to an expansive reception hall drenched in Calcutta gold, premium select marble imported from Italy. Aptly named, Castle on the River is no doubt fit for royalty. Sitting atop a domain of 1.2 wooded, terraced acres in one of Northern Virginia’s most prestigious neighborhoods, this extraordinary estate is the definition of grandeur.
