In August 2003 The Three Tenors sang at a concert to mark the opening of the Thermae Bath Spa, a new hot water spa in the city centre, but delays to the project meant the spa actually opened three years later on 7 August 2006. In 2008, 104 decorated pigs were displayed around the city in a public art event called "King Bladud's Pigs in Bath". It celebrated the city, its origins and artists. Decorated pig sculptures were displayed throughout the summer and were auctioned to raise funds for Two Tunnels Greenway.
