The walkway between pews in a church is called an aisle. The wedding party and bride walk down the aisle to the front of the church. (The groom can enter from any door. He does not walk down the aisle in a formal procession, but waits at the altar for his bride.) However, other weddings not in church do not use a structural "aisle". They might place a "runner", often made of satin, across a lawn to create an "aisle" between chairs for seating.
