  We present high-resolution, long-slit optical spectra and images of the
planetary nebula NGC1514. The position velocity maps of the [OIII] emission
line reveal complex kinematics with multiple structures. A morpho-kinematical
analysis suggests an inner shell, originally spherical and now distorted by
several 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 of
them. Based exclusively on their morphology, we propose a barrel-like structure
to explain the rings. Several ejection processes have been possibly involved in
the formation of the nebula although a time sequence is difficult to establish
with the current data. We also analyze intermediate-resolution, long-slit
spectra with the goal of studying the physical parameters and chemical
abundances of NGC1514. The nebular spectra reveal a moderate-excitation nebula
with weak emission lines of [ArIII], [NeIII], HeI and HeII. No [NII] neither
other low-excitation emission lines are detected. We found an electron
temperature around 14000K in the gas and an electron density in the range of
2000 and 4000 cm$^{-3}$.
