    Step back to a time when St. Lawrence River summers were measured by the sound of passing ships, sunsets from the porch, and generations gathering under one roof. This timeless early-1900s Round Island cottage, ‘ Sonnenklang’ is more than a home, it is an invitation to continue a cherished Thousand Islands tradition. Beautifully preserved with its original woodwork, exquisite central staircase, stained glass window, and craftsmanship are rarely found today. Cedar shake cottage captures the character and warmth of a bygone era. Offering five bedrooms on the second floor, an additional first-floor bedroom, a full bath on the main level and a half bath upstairs, there's room for family and friends to gather comfortably for summers to come. The formal dining room is ready for memorable dinners, while the spacious kitchen features a walk-in pantry, adjoining storage and laundry room, and a back staircase to the second floor, a reminder of the home's historic design. A fireplace in the living room provides warmth on chilly nights. Stretching across the front of the home, the expansive covered porch becomes the heart of the cottage, where you'll enjoy breathtaking sunsets, watch freighters and pleasure boats glide along the channel, experience the peaceful rhythm of river life. Protected dockage makes boating effortless. The detached garage offers abundant storage today and exciting possibilities for future guest accommodations, while the full attic presents additional potential to expand and customize the home to your vision. Offered fully furnished and turnkey, this exceptional property allows the next owner to begin making memories from day one. Round Island itself is one of the Thousand Islands' most treasured communities, featuring a post office, tennis court, scenic walking trails, and a welcoming summer neighborhood. Being just a short boat ride from Clayton and the mainland. Rarely does an authentic Thousand Islands cottage of this caliber become available. Whether preserved in its timeless elegance or thoughtfully enhanced for future generations, this remarkable property is a blank canvas for creating the next chapter of unforgettable summers on the river.
