Antonio Maceo monument, Havana

Batería de la de la Reina, built between 1856 and 1861, was a colonial military defense fortress that had accommodations for a garrison of 250 men and 44 pieces of artillery. It was demolished in 1901. Its site was in the esplanade that today occupies the Antonio Maceo park. The fort was a semi-circular building with a 44-gun battery facing the sea. Its fires intersected with those of the Santa Clara Battery and the “Castillo de la Punta”.

Arcabuco was the name of a footpath starting in Old Havana, in the vicinity of the church of Loma del Ángel, and ran in a westerly direction to an inlet cove of approximately 93 metres (305 ft) wide and 5.5 metres (18 ft) in depth. When Juan Guillén a Spanish soldier installed a carpentry shop to build small boats close to the cove the site became known as “La Caleta de Juan Guillén”, the road was known as “the caleta”. Eventually the Hospital de San Lázaro, the Espada Cemetery, the San Dionisio mental asylum, and La Casa de Beneficencia were developed in close proximity to the Caleta de San Lazaro.

La Casa de Beneficencia y Maternidad de La Habana, (Spanish: The House of Charity and Maternity of Havana) was for 270 years Havana's repository of Havana's unwanted children. The House of Charity started during a time when Cuba was experiencing extreme poverty, unemployment, and corruption in the government. Corrupt leaders were plundering the public treasury and little attention was given to social assistance, health, education, or the protection of the poor: "los desamparados".

The Hermanos Ameijeiras Hospital, officially the Hospital Clínico Quirúrgico "Hermanos Ameijeiras", is located in Barrio San Lazaro and is the premier hospital in Cuba, its tower prominently visible from the Malecón between the historic center and the uptown Vedado neighborhood. It was opened in 1982. According to EcuRed, the Cuban state wiki, it was "created by the Revolution to offer the people service in a best-in-class, world-class environment" ("creada por la revolución para brindar al pueblo una atención en el ámbito de los mejores centros de su clase en el mundo") The hospital is located at San Lázaro and Belascoaín streets in Centro Habana. It has a footprint of 35,500 square metres (8.8 acres), and 79,500 square metres (856,000 sq ft) of floor space. The monumental lobby measures 75 metres (246 ft) by 45 metres (148 ft) with a 15-metre-high (49 ft) ceiling and murals by Romanian-Cuban artist Sandú Darié.

El Torreón de San Lázaro is round tower of masonry built on the shore of the Caleta de San Lazaro. The Torreón de San Lázaro is approximately 4.57 metres (15.0 ft) in diameter and 9.14 metres (30.0 ft) high with embrasures along its wall at the intermediate level and a battlement parapet at the third level roof. It has a wooden entry door at ground level. With the passage of time, the San Lazaro cove was filled and the tower was included in a Republican-era park named after Major General Antonio Maceo. In an 1853 map of Havana it is shown as the Torreón de Vijias (lookouts). In 1982, the Torreón was inscribed along with other historic sites in Old Havana on the UNESCO World Heritage List, because of the city's importance in the European conquest of the New World and its unique architecture.

There is an abandoned Jai alai court in the back of the Hermanos Ameijeiras Hospital, the site of the old Casa de Beneficencia, on Calles Concordia and Lucenas near Calle Belascoain, an area that had been considered in the early part of the city as a place to locate the helpless and the unwanted (Casa de Beneficencia, Hospital de San Lázaro, the Espada Cemetery, Casa de Dementes de San Dionisio), it was the edge of the city and the countryside known as the "basurero"; the spectator stands were parallel to Calle Concordia, the front wall of the court faced Calle Lucenas, east in the direction towards Old Havana. The original building has been annexed by five stories of residential concrete construction on the north side along Calle Virtudes. The Havana Jai alai fronton was known as "the palace of screams" (Spanish: el palacio de los gritos).

Hospital de San Lázaro [1] was a hospital in the city of Havana, Cuba. It dates back to the 17th century, when it served as headquarters for some huts built near the Caleta de Juan Guillén, then known as Caleta de San Lázaro, in an area about a mile outside the city walls.

The Espada Cemetery was located in the Barrio of San Lazaro approximately a mile west of the city walls, near the cove of Juan Guillen and close to the San Lázaro Leper Hospital. In use from 1806 to 1878, the Espada Cemetery was the first public burial place designed and constructed in Havana; prior to the cemetery, the Havana custom had been to bury the dead in the vaults of the churches such as Iglesia del Espíritu Santo in Havava Vieja. It was named after the Bishop incumbent at the time of design, José Díaz de Espada y Landa. Its boundaries included the present streets of San Lázaro, Vapor, Espada, and Aramburu. Despite being officially called Campo Santo, the people of Havana referred to the cemetery as el Cementerio de Espada. The cemetery was closed in 1878 and demolished in 1908, only a small wall remains of the original structure.

The Malecón (officially Avenida de Maceo) is a broad esplanade, roadway, and seawall that stretches for 8 km (5 miles) along the coast in Havana, Cuba, from the mouth of Havana Harbor in Old Havana, along the north side of the Centro Habana neighborhood and the Vedado neighborhood, ending at the mouth of the Almendares River. New businesses are appearing on the esplanade due to economic reforms in Cuba that now allow Cubans to own private businesses.

Cayo Hueso is a consejo popular (ward) in the municipality of Centro Habana, Havana, Cuba. A traditionally working-class neighborhood populated by Afro-Cubans, it is known for its many cultural landmarks such as the Callejón de Hamel, the Fragua Martiana Museum and the Parque de los Mártires Universitarios. Although Cayo Hueso today is considered part of Centro Havana, originally it formed part of Barrio San Lázaro, an area bounded by Calle Infanta to the west, Calle Zanja to the south, Calle Belascoáin to the east and the Gulf of Mexico to the north. Cayo Hueso was declared a barrio on 26 July 1912, and made part of Centro Habana upon its establishment in 1963.

The Humboldt 7 massacre was the extrajudicial killing of four armed Directorio Revolucionario Estudiantil (DRE) members by the Havana police on 20 April 1957. The police, led by Lt. Colonel Esteban Ventura Novo, entered apartment 201 of Humboldt 7, a residential building where the DRE members were hiding. The four men who were killed during the incident had taken part in the Havana Presidential Palace attack and the seizure of the Radio Reloj station at the Radiocentro CMQ Building. Prior to the incident at Humboldt 7 the Havana police were searching for the four men for their involvement in the attacks on the Presidential Palace and the Radiocentro CMQ Building. The men were alleged to have been betrayed by Marcos Rodríguez Alfonso (also known as "Marquitos"), a fellow revolutionary who was against the conflict to remove Fulgencio Batista from power. After an argument with members of the DRE, he informed Lieutenant Colonel Esteban Ventura of their location; police promptly converged on the area and shot the men while they attempted to flee.The incident was referred to as an assassination and a massacre after it occurred, and the event greatly reduced support for the police. The incident was covered up by police officials until a post-revolution investigation. Marquitos was arrested in 1961 and, after a double trial, he was sentenced by the Supreme Court to the penalty of death by firing squad on 2 April 1964.
