My mother and I dropped our bags at the Arriva Hotel near King's Cross and after a quick cuppa at a nearby Costa, we headed to the heart of what Londoners call the City. We had great difficulty finding our goal, the Temple Church, partly because my phone took us in circles and partly because it was hidden away, but it was awesome once we found it. It's a late 12th-century church, church of England's four ancient societies of lawyers and was built by the Knights Templar as their English headquarters.
