Who owns Guantánamo Bay?

Cuba holds ultimate sovereignty over Guantánamo Bay, but under a 1903 lease the United States exercises complete jurisdiction and control. A 1934 treaty made the lease indefinite — it can end only by mutual agreement or if the U.S. abandons the base.

Does the U.S. pay rent for Guantánamo Bay, and how much?

Yes. The lease sets rent at the equivalent of the original 1903 payment — about $4,085 a year (first set at $2,000 in gold coin). The U.S. Treasury still issues the check annually.

Why won't Cuba cash the Guantánamo rent checks?

Cuba considers the U.S. presence illegitimate and has refused the payments since 1959 rather than appear to consent to the lease. Only one check was ever cashed — in 1959, reportedly by confusion; Fidel Castro said the rest were kept in a drawer.

Could Guantánamo Bay be returned to Cuba?

Legally, only by mutual agreement to modify or end the treaty, or if the U.S. abandons the base — the 1934 treaty has no expiration and Cuba cannot end it unilaterally. Cuba has long demanded its return.

How big is Guantánamo Bay Naval Base?

About 45 square miles (116 km²) at the southeastern tip of Cuba, straddling the bay — the oldest overseas U.S. naval base, in operation since 1903.

Guantánamo Bay (Gitmo)

A U.S. naval station on Cuban soil — one of the Caribbean's best natural deep-water harbors and a 120-year legal anomaly. This dossier is informational only.

The layout

The bay splits the base in two: leeward (west), with the airfield, and windward (east), with the base and town. There's no bridge — a ferry crosses. To the north, the fence is the only land border between U.S.- and Cuban-controlled territory.

History

1898

U.S. forces take the bay in the Battle of Guantánamo Bay during the Spanish-American War — chosen for its sheltered deep-water harbor.

1901

The Platt Amendment lets the U.S. lease lands for naval/coaling stations; written into Cuba's 1901 constitution.

1903

The lease grants the U.S. the area for “coaling or naval stations only,” with “complete jurisdiction and control” while Cuba keeps “ultimate sovereignty.” Rent: $2,000 in gold coin/year.

1934

FDR's Treaty of Relations repeals most of the Platt Amendment but preserves the lease — making it effectively perpetual: changeable only by mutual agreement or U.S. abandonment.

1959–61

After the revolution the base becomes a flashpoint: Cuba plants an 8-mile cactus barrier (the “Cactus Curtain”) and both sides lay ~55,000 land mines.

1991–94

Migrant operations: tens of thousands of Haitian and Cuban “balseros” migrants are interdicted and held in tent cities — Operation Sea Signal processed 50,000+.

2002

The detention camp opens (Jan 11) — Camp X-Ray, then the permanent Camp Delta — run by a separate joint command, not the naval station.

Today

The naval station operates as a self-contained American town; the detention facility continues at a reduced scale with 15 detainees remaining (early 2025).

The harbor

Guantánamo is the largest harbor on Cuba's southern coast and one of the Caribbean's best natural deep-water ports — its sheltered outer harbor admits the deepest-draught vessels, and steep hills make it defensible. In 1898 it was a vital coaling base for the fleet blockading Santiago; later, key to defending the Panama Canal and the U.S. southern approaches.

Legal status

The 1903 lease grants the U.S. “complete jurisdiction and control” while recognizing Cuba's “ultimate sovereignty,” with no end date. The rent — originally $2,000 in gold, now cited at ~$4,085/year — has gone uncashed by Cuba since 1959 (with one reported exception, cashed “in error or confusion”). Cuba deems the occupation illegal and demands its return; the U.S. treats it as a valid, in-force treaty. It can end only by mutual agreement or U.S. abandonment — and U.S. law (NDAA, sanctions) adds further hurdles.

The detention facility

Since Jan 11, 2002 (Camp X-Ray, then Camp Delta), the facility has held ~780 people from 48 countries (peak ~680 in 2003). Three Supreme Court rulings shaped its legal framework — Rasul (2004), Hamdan (2006), and Boumediene (2008), which recognized detainees' constitutional right to habeas corpus. 15 detainees remain today (early 2025). It is run by a separate joint command (JTF-GTMO), not the naval station.

The base today

A self-contained American town of ~6,000 residents (military, DoD civilians, contractors and families), with schools, a hospital, retail and chapels. Because Cuba cut utilities after 1959, the base desalinates its own water and generates its own power. Historically, contract workers from Jamaica and the Philippines have made up a large share of the workforce.

Forward scenarios

The realistic range for GTMO's future, taking no side. Any change requires mutual U.S.–Cuba agreement, with high near-term legal barriers.

Status quo

Indefinite continuation under the 1903/1934 lease — backed by the treaty's mutual-consent requirement and current U.S. legal restrictions.

Return to Cuba

Full transfer of jurisdiction to Cuba — Cuba's standing demand and a precondition it has named for full normalization.

Joint / phased use

Negotiated shared use — humanitarian, disaster-response, environmental or migration processing — as a bridge toward eventual return.

Special economic zone / free port

Proposals to convert the deep-water harbor into a free-trade zone or port hub (as Cuba has pursued at Mariel). The “charter city” variant is widely regarded as unlikely.

Fun facts

Cuba won't cash the rent

Decades of ~$4,085 U.S. Treasury checks sit uncashed — Fidel Castro kept them in a desk drawer, having cashed only one, reportedly “in confusion,” early in the revolution.

The only U.S. fast food on Cuban soil

The base has a McDonald's (since 1986), a KFC and a Pizza Hut — open only to base personnel, not ordinary Cubans.

Iguanas with legal protection

The endangered Cuban rock iguana is protected on base under U.S. law — troops are warned that harming one can reportedly bring a fine of up to $10,000.

An island within the island

After Cuba cut its water in 1964, the base built its own desalination plant — it now makes 100% of its own drinking water and electricity.
