This era saw the laying out of the triangular marketplace that became the Bull Ring; the selling of burgage plots on the surrounding frontages granting privileges in the market and freedom from tolls; the diversion of local trade routes towards the new site and its associated crossing of the River Rea at Deritend; the rebuilding of the Birmingham Manor House in stone and probably the first establishment of the parish church of St Martin in the Bull Ring. By the time Peter's son William de Birmingham sought confirmation of the market's status from Richard I twenty three years later, its location was no longer "his castle at Birmingham", but "the town of Birmingham".
