The Yellow House located near the Yeoward coast is a two-storey Canary house, now practically a ruin. In the 1920s it was used as a centre for research into Primate behaviour , run by German scientific institutions and its results of enormous importance. The work on chimpanzees done there by Prof. Wolfgang Köhler and his colleagues from the Prussian Academy were the corner stone of the Gestalt school of psychology, an essential current of thought in the evolution of modern psychology. From the time of the closing of the research centre in 1915, the Yellow House has been abandoned and has deteriorated to become nothing more than a ruin.

In the middle of the XVIIIth Century, the XIth Conde [Count] de la Gomera, married Doña Marina Leonor Benítez de Lugo y Ponte and built a mansion as a wedding present in the area of el Durazno, on land given to him by his father-in-law. He also built an oratory, and adorned it with an image of San Antonio [Saint Anthony]. This house was restored in 1993 and opened to the public as a museum. In the evenings, cocktails are served while classical music is performed. Exquisitely decorated, the Mansion contains unique works of art. To the collection of paintings and tapestries from the XVII and XVIIIth Centuries, Bohemian lamps and Murano crystal, bronze Italian busts and a snooker table from 1922 (one of only five in the world), other items of historical furniture from several European countries have been added.

Next to the Punta del Viento viewpoint is the former convent of Santo Domingo, in the street of the same name. The Order of Saint James finished the construction of the Dominican Convent of San Pedro González Telmo around the year 1659. In 1778 the Convent was devastated by fire. The reconstruction was carried out between 1781 and 1786 by the architect José de Bethencourt y Castro. As a result of the disentailment (enforced sale of Church lands) in 1837, it became State property and was bought by a private individual in 1950. In the XIXth Century, Luis Rodríguez Figueroa was born in this house; an outstanding and learned politician , he was executed during the Spanish Civil War. The Town Council of Puerto de la Cruz recently acquired the building from the Rahn family with the intention of housing the Council offices in it.

This is the oldest civil structure preserved in Puerto de la Cruz and an essential element in any photo of the fishing harbour. Built in traditional Canary style, it was founded in 1620 by the Franchy family. Later on it was leased to the Royal Treasury to house the Customs offices and as a residence for the Chief Customs Officer, until in 1833 this department was transferred to Santa Cruz. Around the Customs House , from 1708 until the beginning of the XXth Century, was the Santa Barbara battery, of which only the stone stairway, built in 1741, leading down to the sea, remains. This small fortification consisted of a crenellated wall, a lookout post and a powder house. It was armed with four cannon to defend the ships anchored in the area of the Limpio de las Carabelas, near the end of the old breakwater. In view if the large number of ships which arrived to load fruit, the Mayor requested the Military Command to knock down the crenellations and the lookout post to allow lorries bringing the goods to manoeuvre. In 1997 the Tenerife Cabildo bought the house from the Baillon family, restored it and turned it into a cultural and exhibition centre. It has too the new Tourist Office on the ground floor.

The mountainside at Martiánez is one of the few natural areas in the Municipality of Puerto de la Cruz. Its impressive 45-metre height inspired one of Agatha Christie’s stories. It is made up of a series of geological strata of different volcanic materials, a natural entity which encompasses an important ecological, historical, ethnographical and archaeological heritage. The Tenerife Cabildo has begun the procedure to have the Martiánez mountainside declared part of the Island Cultural Heritage as an Archaeological Zone. This cliff on which the viewpoint and the suburb of La Paz sit, was, before the Spanish Conquest, a guanche burial ground. In these natural caves, some used as dwelling caves and others for burials, numerous aboriginal remains have been found. Near the caves, there was once the famous Martiánez spring, one of the main sources of water for the population of Puerto. In 1901 pipes were installed from this spring to Chorro Cuaco in Valois Street. Furthermore, the mountainside is renowned for the important native flora, in particular the Canary palms and the tabaiba [Euphorbia]. Formerly there was a footpath, much used by tourists, which descended the hillside and linked the Martiánez beach with the La Paz viewpoint, until a large rock fall necessitated its closure.
