In later times royal persons and great feudal magnates frequently kept menageries of wild animals, aviaries and aquaria, and it is from these that modern public Gardens have taken their origin.
In the New World, according to Prescott, King Nezahualcoyotl had zoological gardens at Tezcuco in Mexico in the middle of the 15th century, whilst in the next century Cortes found aviaries and fishponds at Iztapalapan.
The beautiful Gardens at Cologne, founded in 1860, contain many interesting features and in particular one of the finest aviaries in Europe.
