Abbey Church of the Palace of Holyroodhouse in Edinburgh
Abbey Church of the Palace of Holyroodhouse in Edinburgh was named after
piece of the "true cross" which was brought to Scotland by Princess
Margaret, accompanied by William "the Seemly" Sinclair. Andrew
in his book "The Sword and the Grail," states Henry Sinclair, Third Lord
Roslin, "began the building of Holyrood Abbey and Holyrood House to
the precious relic brought from Hungary." At least seven or eight of
stones in the floor of the abbey are memorials to Sinclairs.
