Myra is in modern day Turkey. Wikipedia has this picture of St. Nicholas' original tomb in Myra,
St. Nicholas Day is rarely celebrated in the Episcopal church, but there is a traditional prayer for the day one can find on the lectionary pages,
Almighty God, who in thy love didst give to thy servant Nicholas of Myra a perpetual name for deeds of kindness on land and sea: Grant, we pray thee, that thy Church may never cease to work for the happiness of children, the safety of sailors, the relief of the poor, and the help of those tossed by tempests of doubt or grief; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, for ever and ever.For more details, go to the Churchmouse's site. As for me, I will put our St. Nicholas ornament on the tree today.
