Pozuelo de Alarcon, Spain

At 89,770 residents, Pozuelo de Alarcón ranks as Spain's wealthiest municipality, but the affluence comes with a heavy tax burden and persistent bureaucratic headaches. This pine-tree-ringed enclave bordering Madrid has become a low-density residential haven for the upper class, with luxury enclaves like La Finca attracting many high-profile residents. However, the cooler climate stemming from its proximity to the mountains is a mixed blessing, as it can make for longer, harsher winters compared to the capital. Overall, Pozuelo is best suited for those seeking an exclusive, tranquil lifestyle within easy reach of Madrid, provided they can navigate the local red tape.
