In 1917 the Royal Flying Corps adopted the existing civilian aerodrome just to the west of Marske, expanding it into a military training establishment.

In April 1918 it came under the control of the newly formed Royal Air Force, with one of the first RAF students being 'Captain' W. E. Johns, the author of the Biggles books.

The 1974 reforms also placed the village under Langbaurgh borough, it was renamed Langbaurgh-on-Tees in 1988 and (since 1996) is named Redcar and Cleveland.

Marske is part of Redcar constituency[8] and is represented by Labour (Co-op) MP Anna Turley in the House of Commons.

[13] The tower of St Germain's church was allowed to remain close to the cliff edge as a prominent landmark for fishermen in the North Sea.

[20] The village has a museum named Winkies Castle, dating back to the 17th century, which is run by volunteers and open to visitors from Easter Saturday each year until the end of September.

This is not really a castle but an old half cruck cottage formerly owned by the late master shoemaker, Jack Anderson.

The museum puts on rotating exhibitions and has over 6,000 items, including a two-headed lamb called "Bill and Ben".

The building was saved from demolition in 1968 by Jack Anderson when he turned it into a community museum and bequeathed it to the Community of Marske (trustees Redcar and Cleveland Borough Council).It is now run and managed by volunteers and is open three days a week from Easter Saturday until the end of September each year.
