The Spanish Royal Family holds properties including the Almudaina Palace in Mallorca as state assets managed under the Patrimonio Nacional agency. The Saudi Royal Family controls thousands of properties through the Saudi Royal Court and major sovereign wealth entities such as the Public Investment Fund, which managed assets exceeding 925 billion dollars in 2024.
