Buttwil is a municipality in the district of Muri in the canton of Aargau in Switzerland. The village is west of Muri. History Buttwil is first mentioned in 1160 as Butwile. From its founding the Benedictine Muri Abbey possessed extensive real estate in the village. With the conquest of Aargau in 1415 the high court right, which had been held by the Habsburgs, went to the Swiss Confederation. The low court right remained at the Abbey. The chapel of St. James was built in 1666 and was a chapel of ease in the Muri parish. This former farming village showed, up about 1950, a steady population decline. This was followed by a sharp increase since 1970 is due to the virtually fog-free area and the short commutes on the train to Zurich and Lucerne. Since 1984 there has been a bus connection to Muri.
