A tomb-shrine to Collen stood in the churchyard until the 19th century, but it was demolished to create space for the current west tower. The core of the church dates to the 13th century, but most of what we see today dates from a renovation in 1864.
The major treasure of St Collen's is the medieval hammer-beam roofs of the nave and north aisle, together forming one of the finest roofs in north Wales. Some stories suggest that the roofs came from nearby Valle Crucis Abbey, but this is debatable.
The roofs are ornamented with figures of angels and fanciful carvings. There is a 14th-century Founder's Tomb in the north aisle and a striking monument in the south aisle to the Ladies of Llangollen (see Plas Newydd). A memorial to the Ladies and their housekeeper Mary Caryll stands outside the church.
In the porch is an 18th-century oak chest with three keyholes; each had to be opened by a churchwarden from one of the three districts within the parish, with separate keys.
Note:
St Collen's seems to have intermittent opening hours, even in mid-summer. If it is closed when you visit you can at least take a look at the Ladies of Llangollen memorial near the south-west corner!
