We present high-resolution, long-slit optical spectra and images of theplanetary nebula NGC1514. The position velocity maps of the [OIII] emissionline reveal complex kinematics with multiple structures. A morpho-kinematicalanalysis suggests an inner shell, originally spherical and now distorted byseveral bubbles, and an attached outer shell. The two well-defined,mid-infrared rings of NGC1514 are not detected in our high-resolution,long-slit spectra, which prevented us from doing a kinematical analysis ofthem. Based exclusively on their morphology, we propose a barrel-like structureto explain the rings. Several ejection processes have been possibly involved inthe formation of the nebula although a time sequence is difficult to establishwith the current data. We also analyze intermediate-resolution, long-slitspectra with the goal of studying the physical parameters and chemicalabundances of NGC1514. The nebular spectra reveal a moderate-excitation nebulawith weak emission lines of [ArIII], [NeIII], HeI and HeII. No [NII] neitherother low-excitation emission lines are detected. We found an electrontemperature around 14000K in the gas and an electron density in the range of2000 and 4000 cm$^{-3}$.
