Berlin's Brandenburg Gate

Brandenburg Gate in Berlin's Mitte district was the city's first Neoclassical structure. Measuring an impressive 26 meters in height - including the Quadriga, the spectacular four-horse chariot carrying the goddess of victory perched atop - its six huge columns on each side of the structure form five impressive passages: four were used by regular traffic, while the center was reserved for the royal carriages.

Undoubtedly Berlin's most iconic structure, it's hard to believe that the majestic structure you see today was severely damaged during WWII and was also once part of the infamous Berlin Wall and, for a few decades, was symbolic of the division of Berlin into East and West.

Cologne Cathedral (Kölner Dom)

The towering Cologne Cathedral (Kölner Dom) - the Cathedral of St. Peter and St. Mary - is located on the banks of the Rhine and is undoubtedly Cologne's most impressive landmark. This masterpiece of High Gothic architecture, one of the largest cathedrals in Europe, was begun in 1248 and was the most ambitious building project of the Middle Ages.

As imposing as its façade, its magnificent interior covers an area of 6,166 square meters and boasts 56 huge pillars. Above the high altar is the Reliquary of the Three Kings, a 12th-century work of art in gold that was designed by Nicholas of Verdun to house the relics of the Three Kings brought here from Milan.

Schwerin Castle

Schwerin Castle in the city of Schwerin is one of the most significant attractions in the state of Mecklenburg-Vorpommern. The castle is situated on an island in the middle of the Schweriner See, adding to its unusual appeal. Built in the 14th century, Schwerin Castle is now a seat of government, and it is open for guided and self-guided tours. The castle is said to be haunted by the ghost of a creature called Petermännchen, and these legends bring in a number of curious visitors each year.

Reichstag in Berlin

The capital city of Berlin is filled with historic buildings, but one of the most important is the Reichstag. Although originally dating back to the 19th century, the Reichstag got a major renovation in the 1990s after being severely damaged in WW2. Following the end of the Cold War, Berlin was chosen as the overall capital, and the Reichstag became the official seat of government in Germany. It now boasts an incredible glass dome that offers views over the city and looks stunning when illuminated at night.

Hohenzollern Castle

The neo-Gothic Hohenzollern Castle is perched on a bluff overlooking two small towns at the foothills of the Swabian Alps. Constructed in the 19th century, the castle is the third to stand in the same spot over the last one thousand years. Hohenzollern Castle is situated with sweeping views over the landscape, and it boasts opulent rooms filled with stained glass windows and decorative frescoes. Family jewels and artifacts can be found in the Schatzkammer, or treasury.
