It looks like today Tobias Menzies and Caitriona Balfe are in the west end of Glasgow filming scenes for season three of Outlander. By the looks of Caitriona and Tobias in costume and the cars, they look to filming Boston scenes from after Claire returns from Jamie. Thanks to the fans and bystanders for taking pictures (and video).
If any more are posted today, we will update this post. Keep checking back.
Update (7:06 PM): More photos added. They moved to shooting at night in the same location and moved up a bit in the timeline (notice the cars).
