Although there was a monastery on this site as early as 1256, the present St. Paul’s Church dates from the late 17th century and exhibits a cheerful clash of spindly Gothic exterior and a calm, white interior with hints of gilded baroque flourish. It is chiefly notable for the unsung collection of paintings by Rubens and his pupil Anthony van Dyck that line the outer aisles. The works of Rubens are “The Flagellation” (painting number 7 of the “Stations of the Cross” sequence in the left-hand aisle) and “The Adoration of the Shepherds” just in front of the choir on the same side. Van Dyck’s contribution was “The Bearing of the Cross” (number 9 in the “Stations of the Cross”). If you get lucky, the choir may perform a 13th-century plainsong during Mass on Sunday morning.
