Mar del Plata Water Tower, Water tower in Stella Maris, Mar del Plata, Argentina.

The Torre Tanque is a 40.75 m Tudor Revival water tower on the highest point of the Loma de Stella Maris, at Falucho and Mendoza. Its shaft of rough-faced tan quartzite, known as Piedra Mar del Plata, carries small rectangular windows and a corbeled stone balcony about halfway up; a lower wing with a steep slate roof and chimney adjoins it, and a small conical-roofed turret with a weather vane stands at left. Below the shaft is a large arched window with vertical stone mullions.

The structure was designed in 1943 by architect C. Lange and marks a period of strong infrastructure development in Mar del Plata during the 20th century. This construction was part of urban modernization efforts and demonstrates the importance of water towers for city growth at that time.

The tower's Tudor Revival design by Cornelio Lange echoes the eclectic summer houses of the Stella Maris hills, and its exterior is clad in Piedra Mar del Plata, the local quartzite. OSSE staff give talks on the water system, and old photographs and newspapers are displayed inside.

Access to the top is available via approximately 194 steps or more conveniently by elevator, with both routes leading to the upper viewing area. Visitors should note that the best sightlines occur during clear weather and opening times may vary seasonally.

The tower's lookout holds at most 50 people at a time, and the climb is 194 steps up a spiral staircase, with an elevator as the alternative. Inside, old photographs and newspapers recount the works carried out before and after the tower was built.
