Trier is home to many old monuments and buildings and boasts a unique history in picturesque surroundings. Trier is the birthplace of the influential philosopher and revolutionary Karl Marx. Take a City Sightseeing tour and discover the city’s rich history as you travel along the route. Hop off at the amphitheatre which dates all the way back to the second century. It is also one of the largest in the Roman Empire. Admire the ruins of the 20,000 capacity arena, which is still used today as a venue for the Antiquity Festival as well as open air concerts. Explore the vast cellar, which housed the prisoners and beasts before they were sent up to the arena and learn of the advanced technological achievements of the ancient Romans. Take the bus tour to Karl-Marx-Haus, where the famous radical was born. The house was opened in 1947 and renovated in 1983 and houses exhibits on Marx's personal history, volumes of poetry, original letters and photographs with personal dedications. There is also the chance to witness a collection of rare first editions and international editions of Marx’s works, as well as displays on the development of socialism in the 19th century. Marvel at the Porta Nigra (Latin for black gate), a large Roman city gate which is today the largest Roman city gate north of the Alps and has been designated a World Heritage Site. At the south side of the Porta Nigra, remains of Roman columns line the last 100m of the street leading to the gate. Take a guided tour in summer months and admire the structure which remains almost untouched by the reconstruction ordered by Napoleon.
