While in Cologne, you can visit Germany's oldest city hall, with parts dating back to the 11th century. Over time, it has picked up a mix of styles—Gothic tower, Renaissance loggia, some modern touches. The 61-metre tower is covered in carved figures, including some cheeky ones from local history, and the bells chime four times a day. There’s also a mechanical face called the Platzjabbek that sticks its tongue out on the hour. Inside, the Hansasaal is the main historic hall—worth a look if it’s open.

This railway and pedestrian bridge is one of the most recognisable spots in Cologne, and hard to miss if you’re near the Cathedral. Originally built in the early 1900s, it was rebuilt after being blown up in 1945. These days, most people come for the view and the thousands of love locks clipped to the railings. It’s a short, easy walk across the Rhine with some great photo angles of the city, especially at sunset.

We all know that a city without its own museum is not a city. Rijeka's City Museum awaits you in the Governor’s Palace Park. The activity of this institution can be seen in various areas, including collecting, treatment and restoration, research of the city’s past and organising exhibitions on important historical themes.

In the northwest corner of Titov Square stands a Baroque chapel with a relief of Madonna with the Child on its front. This passable chapel resembles a small triumphal arch and marks the beginning of the Petar Kružić Stairway that leads to the famous pilgrimage centre, the Franciscan monastery at Trsat. The steps were built in 1531 by order of Warlord Petar Kružić, and were built up over the centuries, up to today's over 500 steps, and adorned with votive chapels.
