  An­tipro­tons are pro­duced at CERN at the An­tipro­ton De­cel­er­a­tor (AD) Tar­get Area by im­pact­ing 26 GeV/c pro­ton beams onto a fixed tar­get. Fur­ther col­lec­tion, mo­men­tum se­lec­tion, and trans­port of the sec­ondary par­ti­cles - in­clud­ing an­tipro­tons - to­wards the AD ring is re­alised by a 400 kA pulsed mag­netic horn and a set of mag­netic dipoles and quadrupoles. A major con­sol­i­da­tion of the area - in op­er­a­tion since the 80s - has taken place dur­ing the CERN Long Shut­down 2 (2019-2021). Among other ac­tiv­i­ties, such up­grade in­cluded: (i) In­stal­la­tion of a new air-cooled tar­get de­sign and man­u­fac­tur­ing of a new batch of mag­netic horns, in­clud­ing a sur­face puls­ing test-bench for their val­i­da­tion and fine-tun­ing (ii) In­stal­la­tion of a new po­si­tion­ing and main­te­nance sys­tem for the tar­get and horn (iii) Re­fur­bish­ment and de­con­t­a­m­i­na­tion of the Tar­get Area and its equip­ment, (iv) Con­struc­tion of a new sur­face ser­vice build­ing to house new nu­clear ven­ti­la­tion sys­tems. This con­tri­bu­tion pre­sents an overview of such ac­tiv­i­ties and les­son learnt. In ad­di­tion, it pro­vides the lat­est re­sults from re­frac­tory met­als R&D for the an­tipro­ton tar­get and a sum­mary of the recom­mis­sion­ing and op­ti­miza­tion plans.
