Places to visit 
19 - URBAN EXPANSION
The town's urban expansion began in the second half of the 19th century, with the building of the new wharf, the Muelle Nuevo or Muelle de Churruca, with the urbanisation of the new land reclaimed from the river estuary. Francisco Orueta laid out five plots: the first and fourth are taken up by the mansions of Calvo and Epalza and the remaining three by residential buildings aligned alongside the river.
20 - THE TIDE RECORDER
This is a decorative item, installed on the Churruca Dock by the Port Development Board around 1883.
As its very name suggests, it is a device used to record the tides. It consists of two clearly differentiated parts: the base and the actual tide recorder itself.
The base is a circular stone podium with ornamental mouldings, and the tide recorder is a circular container that rests upon an iron column, whose base features torus and scotia.
The column shaft is capped by a double annulet. Its capital displays a Tuscan frieze and the Egyptian lotus flower.
The face on the tide recorder is 800 millimetres in diameter and bears the inscription Maremetre / Borrel Wagner / Paris.
21 - THE IRON DOCK
Starting from the Sailing School joining Santurtzi and Portugalete, we have the opportunity to stroll along the 820 metres of the Hierro Quay which, a little further on, reaches out into the waters of the Abra harbour; here, you can enjoy the sea breeze and are sure to meet some amateur fishermen trying their luck.
The quay leading to the centre is called Txurruka, after the engineer who supervised the works on the port, and on which there are some beautiful houses, built by the bourgeoisie in the 19th and 20th centuries.
The interesting example of iron architecture is the palaphitic structure with subsequent fill in with materials between its supports, completed in 1887.
22 - EL SALTILLO MANSION
This mansion stands on the Abaro outcrop, adjacent to Santurce and very close to the Oriol mansion. It was built at the behest of the Vallejo Arana family between 1876 and 1879.
It has a square layout and three storeys. Its cresting clearly testifies to the influence of French architecture.
It underwent major refurbishment in 1950. The facades were cleared of their decorative features, being faced with small panels of reddish brick cladding, giving it the appearance it now has today.
23 - LEJARZA MANSION
This is the mansion standing just beside the park, Parque del Doctor Areilza. It was built in 1883 together with the Chapel, now the parish church, and the Casa de Ejercicios Espirituales (Spiritual Retreat) San Ignacio de Loyola, now the head offices of the open university, the Universidad Nacional de Educación a Distancia, forming an architectural ensemble in a Neoclassical style.
The main building, surrounded by a sprawling garden, features a quadrangular layout with four storeys. The centre of the façade has the ancient coat-of-arms, carved in stone, of the Lejarza family.
24 - DOCTOR AREILZA PARK
It was designed by Emiliano Pagazaurtundua. It is arranged around a central square on the lower part of the slope, precisely where the beach at Portugalete once used to be.
A highlight in one of its corners is a stone fountain that was brought here from the street Calle Coscojales.
It is now time to bring this self-guided tour to a close. We hope you have enjoyed it.
