The Ormaiztegi Viaduct (inaugurated on August 15, 1864) is the town's most emblematic symbol. Designed by engineer Alexander Lavalley, a predecessor of Gustave Eiffel, it stands in a beautiful landscape overlooking the Eztanda River. It is the most important structure on the Madrid-Paris railway line, spanning 289 meters in length and 34 meters in height. Its 18,000 tons are supported by four pillars. The double track was installed in 1912 and electrified in 1928. It is currently disused and forms part of the Basque Country's cultural heritage.

The Plaza de los Fueros is a large rectangular pedestrian street that forms the center of the city and features several good taverns and restaurants with terraces under the arcades. Designed in the mid-19th century, it is a colonnaded square, enclosed on three sides, opening onto a small garden area, behind which is a large esplanade used for a street market on Saturdays. In this square of simple neoclassical buildings, the Town Hall building is particularly striking for its lavish and exuberant decoration.
