The church occupies the site of an original 14th-century chapel dedicated to the sailors of the Bilbao estuary.
The octagonal floor plan is a stylistic rarity for Baroque religious architecture in the Basque Country.
Its construction was necessitated by the severe flooding of the Nervión river, which rendered the older medieval church unusable.
The main altarpiece is considered a significant example of 18th-century woodcarving within the Bizkaia region.
The building was designed by Ignacio de Ibero, one of the most prominent architects in 18th-century Gipuzkoa.
San Nikolas eliza is a distinct Baroque church located in the Casco Viejo district of Bilbao. Designed by architect Ignacio de Ibero, the structure features a unique octagonal floor plan that distinguishes it from traditional rectangular church layouts in the region. The original structure dates back to a 14th-century hermitage that served the local seafaring community. The current church was constructed during the 18th century after the previous medieval building suffered flood damage. Its facade is a prominent example of Basque Baroque architecture, incorporating robust stone masonry and ornate decorative elements. The interior preserves several significant altarpieces, including works by Juan de Mena. The church is dedicated to Saint Nicholas of Bari, the patron saint of sailors. It remains an active parish church integrated into the historical urban fabric of Bilbao.
