The Seven Marvels of Cuban Civil Engineering

Cuba, a vibrant Caribbean nation known for its rich history and culture, is also home to impressive civil engineering feats that have shaped the country’s landscape. From innovative designs to monumental structures, these engineering marvels stand as a testament to Cuba’s engineering prowess and ingenuity. In this article, we will explore the seven marvels of Cuban civil engineering, delving into their architectural significance, historical context, and lasting impact on the nation.

The Civil Engineering Society of the National Union of Architects and Construction Engineers of Cuba (UNAICC) summoned its members in February 1997 to propose the most relevant works of Cuban Civil Engineering across all time and types. After evaluating 36 proposals, a distinguished jury composed of prominent professionals in the field selected the following as the Seven Marvels of Cuban Civil Engineering:

  1. The Albear Aqueduct
  2. Siphon – under the bay – from the Havana Sewer System
  3. The Central Highway of Cuba
  4. FOCSA building
  5. Havana Harbor Tunnel
  6. Bacunayagua Bridge
  7. La Farola Viaduct

The Albear Aqueduct

The Albear Aqueduct, known as the “Acueducto de Albear” in Spanish, is an engineering marvel designed by Colonel of the Infantry and Commander of the Royal Corps of Engineers Francisco de Albear y Fernández de Lara, an influential figure in Cuba´s engineering history. Constructed in the 19th century, this aqueduct provided Havana with a reliable water supply. Its innovative design included a gravity-driven aqueduct system that transported water from the nearby Vento Springs to the heart of Havana. The Albear Aqueduct revolutionized urban development and significantly improved public health. In recognition of its engineering excellence, the aqueduct received a Gold Medal at the Universal Exhibition in Paris in 1878.

Siphon – under the bay – from the Havana Sewer System

Beneath the bustling city of Havana lies a remarkable engineering marvel, a siphon plays a crucial role in the city’s sewer system. The project involved the installation of large-diameter pipes to carry wastewater under the bay. Construction began on June 29, 1908 and was completed on August 26, 1914, with the siphon consisting of a concrete tunnel 2.13 m (7 feet) in diameter. Overcoming engineering challenges, the Havana Sewer System Siphon has been instrumental in maintaining the city’s sanitation infrastructure.

The Central Highway of Cuba

The Central Highway of Cuba, known as the “Carretera Central” in Spanish, serves as a vital transportation artery connecting key cities and regions across the island. Stretching 1,139 kilometers (694 miles), this highway has played a significant role in facilitating trade, tourism, and everyday travel. Its construction began on March 2, 1927, with sections being inaugurated over several years until its official opening on February 2, 1931. The Central Highway passes through sixty cities and towns, including the six provincial capitals at that time, contributing to the country´s transportation infrastructure.

FOCSA Building

The FOCSA Building, completed in 1956, is a remarkable architectural feat in Cuba. It occupies an entire city block with a reinforced concrete structure, standing at 121 m (397 feet) high. Designed by Cuban architects Ernesto Gómez Sampera and Mercedes Díaz, the building consists of 35 stories and contains 373 residential apartments, along with commercial spaces. The FOCSA Building exemplifies the architectural innovation of this time and remains an iconic landmark in Havana.

Havana Harbor Tunnel

The Havana Harbor Tunnel, also known as The Túnel de la Bahía, completed in 1958, revolutionized transportation in the capital city. This underwater tunnel connects the eastern and western parts of Havana, reducing congestion and improving traffic flow. Spanning 733 m (0.45 miles) with four traffic lanes, the tunnel was constructed using advanced engineering techniques to overcome the challenges of excavating through different soil and rock formations. The Havana Harbor Tunnel stands as testament to Cuba´s commitment to modern infrastructure.

Civil engineering

Bacunayagua Bridge

The Bacunayagua Bridge, a stunning engineering marvel, stretches across the Yumurí Valley and serves as a vital transportation link between Havana and Varadero. With a length of 313.50 meters (1,030 feet) and a height of 110 meters (360 feet), it is the highest bridge in Cuba. The bridge’s arch design and robust construction enable smooth traffic flow while offering breathtaking panoramic views. Constructed from 1956 to 1959, he Bacunayagua Bridge showcases Cuba’s ability to overcome geographical challenges while creating a functional and visually stunning structure.

Civil engineering

La Farola Viaduct

Located in the eastern province of Guantánamo, the La Farola Viaduct is an engineering marvel that connects the cities of Baracoa and Guantánamo. Carved through the Sierra Maestra mountain range, this viaduct has transformed transportation in the region, fostering economic development and improving accessibility. Built from April 1964 to December 1965, the viaduct´s construction involved meticulous planning and the use of durable materials, such as reinforced concrete and steel.  The La Farola Viaduct stands as a testament to Cuba´s engineering expertise in conquering challenging terrains.


Cuba’s civil engineering marvels are not only remarkable from a technical standpoint but also represent the country’s rich history, cultural significance, and architectural prowess. From the Albear Aqueduct to the awe-inspiring heights of the Bacunayagua Bridge, each structure tells a unique story of Cuba’s engineering achievements. As the country continues to progress, these marvels will remain enduring testaments to Cuba’s engineering excellence. They have not only shaped the country’s infrastructure but also become symbols of national pride, attracting tourist from around the world.
