The iconic Olympic Sculpture Park of Seattle features an amazing combination of both art and nature. It is interesting to mention that the admission is free, and allows you to observe all art on your own leisure. Some of these interesting art pieces include “Neukom Vivarium”, which is a large greenhouse with various plants and trees. Another piece is “The Schubert Sonata”, a painted steel sculpture to honor musical composers. So when the weather allows it, visit the park and be amazed.

Havana's vibrant Old Town is where the Cuban capital of today took root in the mid-16th century. UNESCO World Heritage Site status has brought about comprehensive restoration work to many of the city's crumbling architectural treasures, built in styles as wide-ranging as Cuban baroque and art nouveau (Plaza Vieja at the heart of Old Havana is where the eclecticism is most evident and best admired from a sidewalk cafe). The Old Town's two main pedestrian thoroughfares – Obispo and Mercaderes – are lined with government-run shops and attractive paladars.

Saarbrücken has plenty to offer to the lovers of architecture, and one unmissable landmark is the city's town hall, built at the turn of the 20th century in neo-Gothic style and designed by Georg Von Hauberrisser, whose works also include the town hall in Munich.
