The park is comfortable for walking with children: wide alleys, lawns, a playground where in the warm season you can splash around in large basins with water, and in the brushwood near the Cascade there is a 3.5 m high stone mammoth hiding. After the end of the World Exhibition, it was supposed to arrange an exhibition of extinct prehistoric animals, but the idea was not developed.
The Castle of Three Dragons (Castell dels Tres Dragons) is another attraction of Barcelona, erected for the 1888 Barcelona Universal Exposition. It was built as a cafe-restaurant and had to be demolished, but then the decision was reconsidered. The castle project belongs to the architect Lluís Domènech i Montaner, the founder of modernism in Catalonia (he is also the author of the Palau de la Música Catalana). Now in this fabulous red brick palace with towers and battlements the Nature Laboratory (Laboratori de Natura) is located. Its exposition includes a collection of rare minerals, stuffed animals, skeletons of birds and animals. As of February 2020, the visit to the center was temporarily suspended for the general public due to reconstruction.
