Cathedral of St Bavo is located at the center of Haarlem and is one of the important landmarks in town. Though the cathedral was first erected in 1245, it has been refurbished completely a couple of times throughout the centuries. The structure we see today has been constructed during the period of 1895 to 1930. Different artefacts saved from the ravages of time can also be found here. This small museum on the premises is also worth a visit.
