Florence Nightingale is now in the Duckwyn app. You can learn about her contributions to the world when you visit Florence, Italy. A memorial to her can be found at Santa Croce. Use the app to find her nearby.

​Florence's tireless work to improve sanitation and the working conditions of field hospitals during the Crimean War helped save thousands of lives. Her important work laid the foundation for the nursing profession. 

You can learn more about her life on Wikipedia.

The Magic Fountain was designed by Carles Buïgas in 1928 for the 1929 Universal Exposition. The fountain uses 3620 jets and over 700 gallons of water to create an impressive visual show. The display times vary based on the time of year. If you're in Barcelona between March and early January be sure to check out the display.

You can check the days and times here.

History

It took just 1 year to complete Buïgas' ambitious project. Over 3000 workers were used to get the fountain ready in time for the Universal Exposition. The first show debuted just one day before the start of the Expo. In the 1980's, music was added to the show to enhance the performance.

One of Duckwyn's passions is hitting the mountains hard. It doesn't matter if it's skiing or snowboarding, he just wants to ride some soft powder. If everything goes well, he'll be carving some turns in Utah next week.

In honor of Duckwyn's love for the mountains, we now have mountain destinations for you to collect. Starting today, you can stamp your passport book when you visit Deer Valley, Brighton, Solitude, Alta, and Snowbird. Even better, when you reach each resorts highest peak, there is a virtual coin for you to collect too. 

Get out, enjoy the winter, and take your Duckwyn app with you. We'll have more mountain resorts coming soon.

Duckwyn needs your help. Three new locations have been added this month in Italy. He'd love to check them out but he needs you to get him there. If you're in Pisa, Milan, or Florence, make sure you use your Duckwyn passport app when you visit the following places:

• Palazzo Vecchio in Florence

• Arco della Pace in Milan

Each place has unique stamps and coins for you to collect in the app. Enjoy your family travels and let us know if there are more historical travel places you'd like to see us add.
