Arribi House
Its broad façade shows us elements of its rich history. The sun-dial is an outstanding feature, as well as the magnificent renaissance portal (in Goienkalea) dating from the XVI century.
Zabala House
With a broad façade looking onto the square, we have a good example of eclectic architecture from about 1896.
The Old Mill of Santa Ana
The old mill of Santa Ana, adjoined to the Arch, was reformed in the XX century. It shows different artistic motifs, some taken from the Cross of Kurutziaga on the initiative of the municipal architect, Eguia.
Under the Plaza Santa Ana ran the water channel that supplied the mill.
Lejarza House
A sixteenth century palace, cubic in character and hermetic, but adapted to the residential prototypes of the Bizcayan renaissance.
On that side facing the Plaza Garitaonaindia we can see the galleries of modernist style which correspond to the enlargement to the rear of the tower, with glazed balconies from the XIX century.
