Cruces de Mayo (Sevilla and Andalusian towns)
Neighborhood associations, hermandades, and pena clubs spend weeks building large floral cross altars in their street or plaza. Municipal juries score them on flower variety, balance, distribution, artistic lighting, traditional Andalusian aesthetic, and festive atmosphere. Specific category prizes are awarded (e.g, Penarroya-Pueblonuevo 2024 winners: Calle Sevilla, Futuro Singular, FAISEM).
Direct municipal competition between cross installations, each anchored to a specific street, plaza, or hermandad's home turf. Public prize ceremony.
Each hermandad/neighborhood association coordinates flower sourcing, structural carpentry, lighting, nightly hosting (8:30pm-midnight required), and serves food and drink to visitors. Collective, multi-week organizing.
A lighter-weight scaffold than Fallas: weeks not months, floral not pyrotechnic. Easier to imitate in BelongHub's tooling. Also a clean example with published municipal rules (the linked PDF gives an actual rulebook structure).

30+ permanent sound systems (Aba Shanti-I, Disya Jeneration since 1985, Killerwatt, Channel One, Rampage, Arts-A-Light, etc.) take over specific street corners across Notting Hill, Westbourne Park, and Ladbroke Grove for the carnival weekend. Each system is a long-running crew with home turf and stylistic identity (roots reggae, ragga, dub, soca, UK garage).
