Bosques also rented a castle and a summer holiday camp near Marseilles to house refugees, claiming that under international law, the property constituted Mexican territory. In 1943, the Gestapo arrested Bosques, his family, and 40 consular staff and detained them in Germany for a year until the Mexican government obtained their release through a prisoner exchange. Cultural legacy Homes in the towns of Nueva Alemania resemble the architectural style of northern Germany, and many of this area's settlers came from the cities of Hamburg, Bremen, and Lübeck. In San Luis Potosí, Sinaloa (Mazatlán) and Veracruz, settlers from Bavaria built structures similar to those found in the Black Forest. The German Cultural Center building in San Luis Potosí is a Bavarian mansion that had been owned by the Baron of Baden-Baden.

Such musical styles are especially popular in northern Mexico and in places of the United States where there is a large immigrant population of Mexican heritage. Many of the dance movements that accompany these styles of music are also rooted in traditional polka step dances as with the square dancing traditions commonly found in vaquero culture Oktoberfest is usually held in several large cities with German-Mexican communities throughout the country, mainly in Mexico City, Chihuahua, and Victoria de Durango.
