Stichting Monumentenzorg Curaçao Stichting Monumentenzorg Curaçao â Curaçao Heritage Foundation â was founded in 1954. The private foundation is the oldest and largest organization in the field of preservation of monuments in the former Netherlands Antilles with over 120 monuments under management, including town houses, forts, plantation houses and even a former synagogue. Several of these were acquired when they were already in a dilapidated state and threatened to be lost. By now most have been restored.
