Castle Hill Inn
In 1874, mining magnate Alexander Agassiz had a sprawling summer house built just outside of Newport. It was an ideal oceanside setting for a man who'd made strides in the field of marine biology. Set on a 40-acre peninsula where the Atlantic meets Narragansett Bay, it was, and still is, a fantastic spot from which to observe marine mammals. Long since put into service as a resort, Agassiz’s Victorian mansion never lost its aristocratic charm, and is one of Newport's most pictureque places to stay. Castle Hill Inn has seven guest rooms and suites—plus a collection of private cottages and houses stationed right alongside the hotel’s private beach. The most dramatic of them occupying a mahogany-trimmed turret with a 360-degree view and a soaking tub overlooking the sea.
