This news clip is a couple of years old, but it covers the yearly celebration of the Feast of St. Thomas Aquinas in Toulouse, the southern French city where the Angelic Doctor’s relics are enshrined.  Toulouse’s old Jacobins (Dominican) church and priory are now state owned (thank you French Revolution!), but the Dominicans there are allowed access to the church once a year to celebrate Aquinas’s feast and venerate his relics.  As you can see, they do it well.
