This church only dates from 1910, but it was built on purpose to house the baroque interior from 1719 of its predecessor. It is interesting to have a look at the baroque carvings. Also noteworthy that this church belongs to the small Old Catholic denomination.

The Rotterdam City Hall may appear quite historic compared to the modern outlook of the city, but it was actually only built in 1915 in a lavish style echoing historic city halls in other Dutch cities. Remarkably, the City Hall survived the bombing and is one of the few truly historic buildings in the city. It is nice to walk into the monumental main hall and see the statues. The courtyard is also worth a look. As the City Hall is still in use you are free to enter the public areas and have a look. The other halls will be off limits, unless you can persuade one of the guards to open the showpiece Burgerzaal for you. The City Hall also has a belltower with carillon which is often played, while the roof of the middle tower is made of gold.
