The Spanish City was founded in 1908 and formally opened in 1910, when a dance hall was added.
The Spanish City, 1910 - Wikipedia commons
In 1920, the Spanish City became the Empress Ballroom. In 1979 the Rotunda Ballroom was converted into the starlight rooms for live entertainment.
Its funfair was extremely popular with fairground rides and amusements, including a 'Corkscrew' roller coaster—which has now moved to Flamingoland in Yorkshire—ghost train and the waltzers, the House that Jack Built, and the Fun House.
Its centrepiece was its distinctive dome, now a Grade 2 listed building; when it was built it was believed to be the second largest unsupported concrete dome in the UK. There are towers on either side of the entrance to the fairground, and situated on top of them two half-life-size female lead figures, one carrying a cymbal, the other a tambourine. The building's architects were from a local firm.
The Dome has had a number of uses over the years as a ballroom, amusement arcade, and Laser Quest Laser Tag Arena.
The band Dire Straits immortalized the Spanish City in their 1980 Mark Knopfler song, "Tunnel of Love," and thereafter the song was played every morning when the park opened. Cullercoats and Whitley Bay are also mentioned in the song.
All things considered, it lasted a long time but was mostly demolished in the late 1990s.
