Visualising WKT geometry string in QGIS

A very simple question: Is there a simple tool in QGIS to graphically visualise geometry formatted as text?

Example geometry:

"POLYGON((571178 6337246,571178 6402217,598061 6402217,598061 6337246,571178 6337246))"

Result:

A layer in QGIS showing the polygon from above.

The intention is to do quick and dirty visualisation for debugging purposes - I feel it is easier to relate to a graphical representation than a coordinate list.
