Translation:My father went to a castle yesterday.
I heard from many native speakers that "ging" (simple past tense, das Präteritum in general) is used mainly in written language, but is rarely used in spoken language.
Is that right?
For example, while people speak they say "Ich bin gegangen", But when it is written, they may write "Ich ging"
Is this true?
English sentences have quite a rigid word order: if not first, the time adverb usually goes last (cf https://dictionary.cambridge.org/grammar/british-grammar/about-adjectives-and-adverbs/adverbs-and-adverb-phrases-position)

But yes, as you point out, he used a definite article when he should have used an indefinite article as well as made an incorrect translation for Schloss.
