Images of the ELAIS-N1 region in polarized intensity (PI) observed with the 28 WSRT mosaic pointings at 350 MHz (based on preliminary calibration and analysis). The images are given at Faraday depths of –8, 0, +8, +16 rad m^-2. Images are 8.2° × 8.2° in size with a PSF of 2′ × 3′ and the noise level is 0.4 mJy PSF^-1 RMSF^-1. The images have not been corrected for polarization noise bias.
