Step back in time with this stately Queen Anne Victorian, a true testament to Helena's storied heritage. With fresh deep green siding, crisp white trim, layered gables, a brand new roof, and a covered front porch with stone-base pillars, this home delivers the charm and craftsmanship of the late 1800s with a few key improvements. Inside, find delightful details like the turret room with its ornate fireplace focal point, sprawling hardwood flooring, stained glass in the upstairs sitting room, and an attic dormer. For all its historic charm, the layout is one that stood the test of time — a functional floor plan with a ¾ bathroom tucked just off the kitchen, three bedrooms and a full bathroom on the second floor, plus a versatile fourth bedroom on the third floor. It's the kind of arrangement that feels as livable today as it did when it was built. With over 3,000 square feet of indoor living space, you also get to enjoy a single car attached garage, and a private backyard space protected by mature trees creating a secret garden effect. Outside you'll notice one of the most coveted backdrops in town — sweeping views of the iconic Helena Cathedral, framed by the rolling hills of Mount Helena and beyond. You're just minutes from downtown shops, dining, and galleries. 620 N Warren St. is a distinctive home in an unbeatable location, awaiting your thoughtful restoration.
