Frankfurt brings together the best of medieval and modern architecture in a beautiful riot of colour. Whether you’re looking to explore the cobblestone paths of the Old Town or gawk at the magnificence of their glass and steel skyscrapers, here’s the definitive guide to the city’s must-see marvels.
Haus Romer
Frankfurt locals are extremely protective of their beloved City Hall, and it’s easy to see why. Some sections of the building date back to the Middle Ages, and it served as Frankfurt’s main hall for over six centuries. Much of the restoration costs of the hall after World War II came out of the pockets of locals.
Main Tower
Germany’s fourth tallest building is an iconic part of the Frankfurt skyline. With an observation deck that offers panoramic views of the city, this is one of the only skyscrapers in Frankfurt that can be accessed by the public. Float 200 metres above ground with a quick elevator ride up 56 floors – tickets start from under ten Euros for adults.
Palmengarten
The Palmengarten is one of Frankfurt’s three botanical gardens, and truly a sight to behold. Designed by Heinrich Siesmayer in the late 1800s, the modern building features a number of beautiful greenhouses that contrast with the original redbrick of the main buildings. Most noteworthy of the greenhouses is the stunning Tropicarium, which is rendered in metal and glass and reflects the water lillies in the pond in front.
Alte Oper
During its prime, this opera house was graced by the likes of Richard Wagner and Giacomo Puccini. Designed in the 1880s, this historic building barely survived the devastation of World War II, but was reconstructed using the funds of residents. Many of the original reliefs and frescoes were restored to their former glory, so the opera house is resplendent in its former glory today.
Cathedral of Saint Bartholomew

The Imperial Church is the main church of Frankfurt and an icon of the city. Some parts of the church date back to the 7th Century, and it was a significant coronation site for the Holy Roman Empire. Featuring an ancient retable depicting the life of Christ, a Romanesque floor plan, and a 328-step spire that guests can climb, this medieval marvel is well worth a visit.
