Over their 25 years in business, their clients have only rarely become public knowledge: Bezos and Sánchez, Salma Hayek and François-Henri Pinault, as well as George and Amal Clooney. All of them got married in Venice, the latter couple doing so at the La Fenice opera house. “Because of our family connections, we always know someone who can open the secret doors in Italy,” di Baucina once told Forbes.

The Lanza & Baucina weddings published in Vogue offer a rare glimpse into their planning style, which often involves a ceremony at a grand historic site followed by a spectacular party. (The planners are known for creating—even building—temporary custom nightclubs and beach clubs for some of their clients.)

Take one three-day wedding in Palermo, Italy. It began with a welcome party at Botteghe Colletti, followed by a three-hour rehearsal dinner at the Villa Igea, where long tables were covered with Lisa Corti tablecloths. It culminated with nuptials at the 18th-century Villa Valguarnera, where Maggie Rogers performed. (“Our planners Riccardo Lanza of Lanza & Baucina were amazing,” said bride Tracy Dubb of the end result.) They also helped Lizzie Edelman and Philipp Sachs marry at the La Citadelle, a historic fort at the top of St. Tropez. The next night, they held a ’70s-disco-inspired “La Nuit Tropezienne” party at the groom’s home, where Lanza & Baucina “lit up the palm trees and the light changed to the beat of the music,” Edelman said.

At a Lanza & Baucina winter wedding in St. Mortiz, the couple’s ceremony on the ice rink of Badrutt’s Palace included a 15-person figure skating routine. During their dinner at the legendary five-star hotel, “The Dance of the Sugar Plum Fairy” from The Nutcracker was performed by dancers from La Scala, the Paris Opera, and the English National Ballet. Finally, Lanza & Baucina turned the hotel’s cinema into a moody red nightclub. The bride, Polina Shaker, told Vogue that “all the details were carefully thought out by Lanza and Baucina.” (Indeed, the wedding planners are said to have a warehouse where they physically stage decor for a couple’s wedding in advance for their review.)
