I'll try to translate the information in Englisch:
Jakob Fugger the rich founded the Fuggerei in 1521 as a social settlement for needy citizens of Augsburg. The annual rent (excluding heating) for an apartment is still the nominal value of one Rhine guilder (currently 0,88 €) as well as three different prayers per day for the founder and Fugger familiy. Presently 150 persons occupy 140 apartments in 67 buildings. The most prominent resident was the master builder Franz Mozart, the great-grandfather of the composer Wolfgang Amadeus Mozart.
The Fuggerei is not only unique in age, but also in continuity: The social settlement is still financed exclusively trhough an endowment. And still today, the conception is considered exemplary. The Fuggerei is not only a shining exemple of architecture now as it also was in the past. The concept was already groundbreaking nearly 500 years ago: Jakob Fugger did not allow residents to become paupers, but rendered assistance for self-help. With this concept, the founder was much ahead of the demands made by Reformer Martin Luther and later Catholic social reformers.
