Filming of “Poldark” season 4 recently took place in Bristol. The crew’s trailers were spotted at Lloyds Amphitheatre, which reportedly served as a unit base for the team. The actual production took place at undisclosed locations.

According to a report by Bristol Post, filming of the series is taking place at Bottle Yard Studios, Whitchurch, in Frome and Wells in Somerset, and other onsite locations. There was a lot of excitement when the crew’s trailers were spotted in Lloyds Amphitheatre, but a spokesperson for Bristol Film Office has confirmed that no filming took place at the location and that it was used a base.

Actual filming took place at three “private” locations. Details about which cast members were involved in the production have not been revealed.

Filming appears to have been completed at these “private” locations, as the crew apparently left by Monday evening. The production is said to have taken place the whole day and the night before.

As far as the plot is concerned, Ross (Aidan Turner) will challenge George Warleggan (Jack Farthing) for the parliament seat. The miner’s political journey will not be an easy one, as the report states he will risk “everything” to help the people of the town.

The plot is set in 1796. Demelza (Eleanor Tomlinson) will have her loyalties torn, Elizabeth (Heida Reed) will strengthen her marriage, Morwenna (Ellise Chappell) will continue to be oppressed by her husband, and the couple Dwight Enys (Luke Norris) and Caroline (Gabriella Wilde) will be tested like never before.

“Poldark” season 4 is set to air in summer this year. There will be eight episodes this year. Karen Thrussell, from production company Mammoth, said that the producers feel this will be their strongest series yet.
