Real Madrid are returning to Pamplona to take on Osasuna again and in doing so they'll visit one of the most hostile cities that they've had to go to in their history.
In terms of rivalry and feelings towards Los Blancos, Pamplona equals even Barcelona.
The political and social climate in the 1980s elevated what happened on the pitch, and generated huge tension around the fixture whenever the two sides met.
But there was a time when Madrid were welcomed in Pamplona, even if maybe it was on just one of their 37 visits there.
In the countryside of San Juan
On April 4, 1936, Madrid were challenging Athletic Club for the title and they made their first trip to Pamplona for a league game.
Two years earlier they had won 3-0 in the Copa del Rey's last 16.
Played at a stadium in San Juan, a neighbourhood not too far from the old town, the pitch wasn't ideal for anyone.
The previous season it had been closed for two games due to incidents in the stands against Sevilla which even led to the suspension of that game with 20 minutes left to play.
"Dozens of cars arrived from nearby places, but not so much from the Navarrese capital," read the local papers at the time.
In 1967 though the team left San Juan for El Sadar.
With Zamora in charge
Madrid arrived led by Ricardo Zamora and were received with a huge ovation, something that was amplified by the presence of the mythical former goalkeeper.
He had been the world's No.1 and shone at the World Cup, becoming a star way beyond the football pitch.
With Osasuna fighting against relegation, the game was played with tension on the pitch. But Madrid came out on top with a 4-1 win, thanks largely to a hat-trick from Luis Regueiro.
Iturralde's grandfather
When referee Eduardo Iturralde Gorostiaga - Iturralde Gonzalez's grandfather - brought an end to the game both teams left the field to an ovation from a packed stadium.
It's unlikely that Madrid will enjoy similar applause this weekend, and Los Blancos aren't so fondly thought of in that part of Spain anymore.
In the 1980s the tension grew. In 1982 a pig was released in a white shirt wearing Juanito's No.7, a bottle has since been thrown onto the pitch, as has a firework and a lighter was thrown at Iker Casillas as recently as 2006.
