This small park is built to honor the memory of the naturalist Friedrich Wilhelm Heinrich Alexander von Humboldt that stayed in the house, facing the park. There are a few benches and some trees, as usual in similar parks.  At the back of the park there is the bronze bust of Alexander von Humboldt, placed on a stone pedestal.

The most interesting feature of the park is a modern sculpture, unveiled on the 200th birthday of Juan Grundlach in 2010. Juan Cristóbal Gundlach (1810-1896), born as Johannes Christoph Gundlach in Marburg, Germany, was a Cuban naturalist and taxonomist (classification specialist). In 1986, on the 90th anniversary of his death, Cuba issued a series of postal stamps commemorating Gundlach. The sculpture is the work of Cuban sculptor Pavel Valdés and depicts Gundlach's bronze head and arms emerging from concrete blocks decorated with bird and insect reliefs and holding a large book.

There is also the bust of Santiago Ramón y Cajal. Santiago Ramón y Cajal (1852-1934) is a Spanish pathologist, histologist, neuroscientist that had won the Nobel Prize with Camillo Golgi in Physiology or Medicine in 1906. Cajal was recognized by many as the father of modern neuroscience for his original and pioneering research on the microscopic structure of the brain.

The Parque Humboldt is located on the Oficios street, where it intersects with the Muralla street.
