Madrid is implementing massive traffic closures and security measures to prepare for the visit of Pope Leon XIV starting June 6 [1].

The scale of the preparations reflects the significant diplomatic and religious importance of the visit, which is expected to draw large crowds and disrupt normal city operations.

City officials have coordinated a comprehensive transformation of public spaces. Approximately 100,000 flowers will be placed in plazas and gardens across the capital [2]. To facilitate movement during the event, the city is providing free bus services and has wrapped buses in themed vinyl [3]. Some museums will also remain open for free throughout the night [3].

Security is a primary focus for the administration. A total of 4,000 municipal police officers will be deployed to ensure safety [4]. This heightened security operation is scheduled to last for four days [4].

Traffic disruptions are most acute around Plaza de Lima, where significant road closures have been established to accommodate the Pope's arrival and scheduled events [5]. As part of the historic welcome, Mayor José Luis Martínez-Almeida said he will present the Pope with the Golden Key to the city [6].

Pope Leon XIV is scheduled to remain in Spain from June 6 to 12 [1]. The city's efforts to "dress in white and yellow" involve not only floral arrangements, but also the installation of Vatican-themed lighting across various districts [2].

The extensive mobilization of 4,000 police officers and the sweeping closure of central hubs like Plaza de Lima indicate that the Spanish government views the visit as a high-security event. By combining strict security with public incentives—such as free transit and museum access—Madrid is attempting to balance the logistical burden of a papal visit with the desire to maintain public order and civic enthusiasm.
