Built in 1785 by General John Brewer, a shipbuilder, this historic home known as the Mansion House has endured the test of time. Standing proud, she looks over the St Croix River and the Passamaquoddy Bay as others would in the past from her glassed-in cupola with an eye out for the British ships in the War of 1812 - that is the legend anyhow. There was an addition in 1821 and history tells us the Greek Revival porch with 4 columns was added in the 1860's. Also referred to as the Mount Vernon of the St. Croix, this strikingly beautiful home boasts of a double central stairway, fan lights, a large piazza with four columns - a grand spot to sit and take in views of the bay and Canada. There are six bedrooms, two that are are Master suites, 4 full bathrooms and one 1/2 bath in this home of over 6000 square feet. Six fireplaces throughout the home. Gorgeous, well manicured lawn, open fields, an apple orchard and wooded areas comprise the 11 acres. AND over 780 feet of easy-to-get-to water frontage that conveys with the property. For your sailboat or motorboat, boat mooring conveys with property. Also public boat launch is literally seconds away. And there is more - a garage next door with apartment above, a boathouse at the waters' edge and a favorite spot of mine, a rustic log cabin with striking water views. There is so much potential here for an Inn, wedding venue and retreat center, family compound. The Sellers have invested an enormous amount of time, money and resources since their purchase and a list will be provided stating the work that has been completed to date. Like my dear friends, the sellers, this was a wonderful home for family. .. what will your vision be for this lovely property?
