It was great to see the place my parents were born and raised.

There are two mistakes here. One is the lack of capital letter in the first word- remember that the first word of a sentence must always begin with a capital letter. The other is grammatical - you have missed out the auxiliary verb 'were'. The sentence should be: It was great to see the place where my parents were born and brought up. Both verbs in this sentence are in the passive voice, so you need to have the verb 'to be' ( in this case 'were' - past simple plural) followed by the past participle of the main verb 'born' and 'brought'.
