Key Colony Beach History: From Shelter Key to a Seaside City — A Quick Guide for Glunz Guests

If you’re dreaming of quiet beaches, walkable streets, and unhurried island time, learning a bit of Key Colony Beach history adds depth to every sunrise and sunset. This quick guide traces how Shelter Key became Key Colony Beach in 1957, and how Glunz Ocean Beach Hotel & Resort grew up alongside the city itself—giving today’s guests a front-row seat to living history right on the Atlantic Ocean.

From Shelter Key to a Planned Coastal Community

Before the city existed, the island was known as Shelter Key—a low-lying, flood-prone stretch with limited development potential. In the early to mid-1950s, a transformative effort began: dredging and filling surrounding waters to raise the land and shape a thoughtfully planned community.

The work created the foundation for canals, waterfront homes, and oceanfront hospitality.
Rather than evolving by accident, the island was intentionally designed for a relaxed, walkable lifestyle with water at its heart.

This era set the tone for what makes Key Colony Beach special today: purposeful planning, community-minded growth, and easy access to the best of the Middle Keys.

1957: A City Is Born

On September 24, 1957, Key Colony Beach was officially incorporated as its own city through a special act of the Florida Legislature. The vote was unanimous, affirming the community’s desire to remain independent rather than join nearby Marathon.

Why independence? Residents wanted to preserve a self-governed, close-knit community with a distinct identity. That choice still shapes the atmosphere today—friendly, small-scale, and proudly local.

A Hotel Rises With the Island

As the island took shape, one of its signature landmarks rose alongside it. Glunz Ocean Beach Hotel & Resort began construction in late 1956, was completed in 1957, and opened the same year Key Colony Beach was incorporated. That timing makes Glunz more than a place to stay—it’s a living part of Key Colony Beach history.

Today, guests enjoy:

Direct beach access and stunning ocean views from a beachfront location at 351 East Ocean Drive in Key Colony Beach.
A private, 600-foot swimmable beach with space to relax.
Family-friendly amenities, including complimentary kayaks, paddleboards, and bicycles.

Resilience Tested: Hurricane Donna (1960)

In 1960, Hurricane Donna struck the Florida Keys with devastating force. Much of Key Colony Beach sustained damage, but the city’s incorporated status proved pivotal. As a recognized municipality, Key Colony Beach qualified for direct federal disaster assistance, enabling faster rebuilding and long-term resilience. The experience fortified the city’s strong sense of community—one that continues to welcome visitors with warmth and care.

Key Colony Beach Today: Small, Friendly, and Unhurried

Modern Key Colony Beach has fewer than 1,000 year-round residents, with seasonal visitors returning year after year. Sunsets are still events. Neighbors still know each other. The pace remains refreshingly unhurried.

Location: Mile Marker 53.5 on the Overseas Highway (U.S. Route 1) in the heart of the Middle Keys.
Reputation: Often called the “Gem of the Florida Keys,” combining ocean views, canal living, and a calm, walkable layout.
Stay: Experience the island’s original spirit at Glunz—right on the ocean and rooted in the same era that gave rise to the city itself.
