Casco Viejo (Siete Calles)

A neighbourhood from 1300 that's still Bilbao's living room

The Casco Viejo isn't a monument with a ticket booth — it's the neighbourhood where Bilbao began and where locals still meet for dinner. It was born in 1300, when Diego López de Haro, 11th Lord of Biscay, granted the founding charter to the settlers of the enclave. At first there were only three streets — Somera, Artecalle and Tendería — and as the town grew, four more were added to form the Seven Streets that give the neighbourhood its name: Somera, Artekale, Tendería, Belostikale, Carnicería Vieja, Barrenkale and Barrenkale Barrena. The names read like a catalogue of medieval trades: cloth was sold on Tendería, meat on Carnicería Vieja. That's the reason it's worth the visit: you're walking on the town's original layout, not a reconstruction. On Somera street, composer Juan Crisóstomo de Arriaga was born on 27 January 1806; his precocious talent earned him the nickname "the Spanish Mozart", the kind of detail that explains why these seven short streets carry so much history. The other draw sits at the edge of the neighbourhood: the Ribera Market, holder of a Guinness World Record as Europe's largest covered municipal food market (worth checking the record's current status and opening hours on an official source before you go).

Price, hours and when to avoid the crowds

Walking around the Casco Viejo is free and there's nothing to book online — it's public street, open at any hour. What does have set hours is what's inside. Shops open roughly from 10:00 to 13:30 and 17:00 to 20:00, and many close on Sundays (except the most touristy ones). The Ribera Market runs on its own market schedule, and specific monuments like the Cathedral of Santiago or the nearby Begoña Basilica have separate mass and visiting hours, with occasional closures for events: check each one at bilbaoturismo.net or its official website on the day.

To avoid crowds, go early on a weekday morning, before 11:00. The opposite is Saturday evening/night and Sunday around midday, peak time for pintxos and family strolls. And a local heads-up: if Athletic Bilbao are playing at home in San Mamés, the bars in the Casco fill up well beyond normal; worth checking the fixture list if your visit falls on a weekend.

How to get there and how much time to set aside

The simplest way is the metro: the stop is called "Casco Viejo" and both Line 1 and Line 2 stop there, so wherever you're coming from you won't need an odd transfer. There's also the Euskotran tram (Line 1, Ribera/Casco Viejo stop) and several Bilbobus routes. Coming from the Guggenheim, skip transport altogether: it's a 10-15 minute walk along the estuary, and the stroll is part of the experience.

Allow 2-3 hours to cover the seven streets and the squares — Plaza Nueva and the Cathedral of Santiago are must-stops — with a pintxos break along the way. Add the Ribera Market and unhurried browsing, and it easily turns into half a day. Two practical notes from the ground: the neighbourhood has had ongoing pedestrianisation works for years, so a street here or there may be dug up, and the cobblestones call for comfortable shoes. Bar and restaurant prices vary a lot from one place to the next; check the menu at the door before sitting down.
