Isla Demarchi, Industrial island in La Boca, Argentina.
Isla Demarchi is an industrial island in La Boca at the southern edge of Puerto Madero, featuring shipyards, port warehouses, and the Costanera power plant. The location serves as a hub for maritime activity and port administration in this part of Buenos Aires.
What began as a sandbank near the Riachuelo was purchased in the 19th century by Antonio Demarchi and his brothers, who transformed it into an industrial zone. This development made the island a key center for port and naval operations.
The island once hosted the first playing fields of River Plate and Boca Juniors before both clubs moved to different areas of the city. This sporting past remains part of the local identity and connection to Buenos Aires football history.
The area is used by port and naval authorities and private companies, making it not readily accessible for casual visitors. A visit typically requires permission or participation in guided tours offered by local organizations.
The National Naval Arsenal, established in 1879, continues to operate and maintains Argentine Navy vessels on the island. This historic facility makes the site an important military and technical center.
