This building is in the middle of Queen Street, one of the main shopping streets in Cardiff town centre. It wouldn’t look out of place in Baghdad.
A plaque on the front of the building, which is in very good condition and looks like it has been renovated fairly recently, reveals that it was built in 1870. It’s a good example of how the Victorians would pinch architectural styles from just about anywhere.
I’ve tried searching on the Internet to try and find out about it, who it was built for, who the architect was, and why it was built in this style, but without any success.
