This year's main structure pays homage to the Consulate of Portugal and the Carlos V gazebo of the Alcázar, commemorating the 500th anniversary of the marriage between the monarch and Queen Isabel of Portugal, a historic event celebrated in the city. Over 28,000 LED bulbs will light up this impressive construction.

The fairgrounds in Seville feature a large main entrance: 40 meters high and wide, 5.70 meters deep, over 30,500 meters of tubing, and nearly 3,800 square meters of paneling. Its construction required more than 6,000 carpentry pieces. In addition to its main design, the entrance incorporates references to local anniversaries, such as the 50th anniversary of Tussam and the centenary of the birth of a prominent noble figure.

Regarding mobility, the Seville Metro will operate continuously throughout the Fair, with a 127% increase in its usual service, reaching 164 continuous hours. Urban bus services will offer 1.7 million seats per direction, 45% more than in a normal week, with shuttle buses and reinforced lines. A new feature is the extension of the tram-bus route to the fairgrounds, with frequencies of 6 to 8 minutes.

The City Council will deploy a health operation with over 130 professionals and 24-hour permanent care, including 23 ambulances and an advanced assistance post. A breastfeeding support service will be incorporated into the Niños Perdidos booth. Security will be handled by over 1,000 local police officers, supported by new AI-powered cameras to monitor crowd flow. For cleaning, nearly 600 workers and over a hundred vehicles will maintain the site.

Hotel occupancy in the city has reached 83%, reflecting the interest in the celebration. Furthermore, the fairground's electrical infrastructures have been modernized, eliminating old overhead lines to improve safety and energy efficiency.
