The Dixon Studio Theatre - University of York

Information
Description: 
Inside Wentworth College at the University of York, this small theatre is host to small intimate audiences. Used mostly for unamplified performances, the space has 3 blocks of tiered seating to the stage left, right and centre. The room was measured without an audience and without the curtains extended. The 5 measurement positions and speaker placement are shown in the images. The positions were chosen to address possible scenarios of a theatre performance. The first 3 measurements were taken in the centre of the 3 tiered seating areas at 1.2m (sitting ear height). These are typical seating positions for a performance. The 4th with a height of 1.5m was chosen to mimic what a performer may hear whilst on stage. The 5th with a height of 1.5m is to emulate an audience member arriving late and staying near the entrance so as not to disturb the performance.

Arbroath Abbey Sacristy

Information
Description: 
Arbroath Abbey is a testament to the integration of piety and politics by Scotland’s medieval monarchs. It was founded in 1178 by King William I ‘the Lion’, ostensibly as a memorial to his childhood friend Thomas Becket, Archbishop of Canterbury, who was murdered in 1170. It also helped him to expand his authority in the north-east of Scotland, and to demonstrate his right to rule. William invited the Tironensian monks from Kelso Abbey, near the English border, to establish the monastery. When he died in 1214, his body was buried before the high altar. Traditionally, Scottish monarchs had been laid to rest at the royal mausoleum at Dunfermline Abbey. The legacy of William’s efforts is an outstandingly beautiful building. It has suffered much damage, but remains an important symbol and landmark. http://www.historic-scotland.gov.uk/propertyresults/propertyabout.htm?PropID=PL_013&PropName=Arbroath%20Abbey
